Fatty acyl-CoA reductase [Caenorhabditis elegans]

Protein Classification

fatty acyl-CoA reductase( domain architecture ID 10859931)

fatty acyl-CoA reductase is an extended SDR (short-chain dehydrogenase/reductase) family NAD(P)-dependent oxidoreductase that catalyzes the reduction of saturated and unsaturated C16 or C18 fatty acyl-CoA to fatty alcohols; in addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids

fatty acyl CoA reductases (FARs), extended (e) SDRs; SDRs are Rossmann-fold NAD(P)H-binding proteins, many of which may function as fatty acyl CoA reductases (FAR), acting on medium and long chain fatty acids, and have been reported to be involved in diverse processes such as biosynthesis of insect pheromones, plant cuticular wax production, and mammalian wax biosynthesis. In Arabidopsis thaliana, proteins with this particular architecture have also been identified as the MALE STERILITY 2 (MS2) gene product, which is implicated in male gametogenesis. Mutations in MS2 inhibit the synthesis of exine (sporopollenin), rendering plants unable to reduce pollen wall fatty acids to corresponding alcohols. This N-terminal domain shares the catalytic triad (but not the upstream Asn) and characteristic NADP-binding motif of the extended SDR family. Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids. Extended SDRs are a diverse collection of proteins, and include isomerases, epimerases, oxidoreductases, and lyases; they typically have a TGXXGXXG cofactor binding motif. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs. Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

356-447 4.62e-28

C-terminal domain of fatty acyl CoA reductases; C-terminal domain of fatty acyl CoA reductases, a family of SDR-like proteins. SDRs or short-chain dehydrogenases/reductases are Rossmann-fold NAD(P)H-binding proteins. Many proteins in this FAR_C family may function as fatty acyl-CoA reductases (FARs), acting on medium and long chain fatty acids, and have been reported to be involved in diverse processes such as the biosynthesis of insect pheromones, plant cuticular wax production, and mammalian wax biosynthesis. In Arabidopsis thaliana, proteins with this particular architecture have also been identified as the MALE STERILITY 2 (MS2) gene product, which is implicated in male gametogenesis. Mutations in MS2 inhibit the synthesis of exine (sporopollenin), rendering plants unable to reduce pollen wall fatty acids to corresponding alcohols. The function of this C-terminal domain is unclear.

13-230 4.92e-19

thioester reductase domain; This model includes the terminal domain from the fungal alpha aminoadipate reductase enzyme (also known as aminoadipate semialdehyde dehydrogenase) which is involved in the biosynthesis of lysine, as well as the reductase-containing component of the myxochelin biosynthetic gene cluster, MxcG. The mechanism of reduction involves activation of the substrate by adenylation and transfer to a covalently-linked pantetheine cofactor as a thioester. This thioester is then reduced to give an aldehyde (thus releasing the product) and a regenerated pantetheine thiol. (In myxochelin biosynthesis this aldehyde is further reduced to an alcohol or converted to an amine by an aminotransferase.) This is a fundamentally different reaction than beta-ketoreductase domains of polyketide synthases which act at a carbonyl two carbons removed from the thioester and forms an alcohol as a product. This domain is invariably found at the C-terminus of the proteins which contain it (presumably because it results in the release of the product). The majority of hits to this model are non-ribosomal peptide synthetases in which this domain is similarly located proximal to a thiolation domain (pfam00550). In some cases this domain is found at the end of a polyketide synthetase enzyme, but is unlike ketoreductase domains which are found before the thiolase domains. Exceptions to this observed relationship with the thiolase domain include three proteins which consist of stand-alone reductase domains (GP|466833 from M. leprae, GP|435954 from Anabaena and OMNI|NTL02SC1199 from Strep. coelicolor) and one protein (OMNI|NTL01NS2636 from Nostoc) which contains N-terminal homology with a small group of hypothetical proteins but no evidence of a thiolation domain next to the putative reductase domain. Below the noise cutoff to this model are proteins containing more distantly related ketoreductase and dehydratase/epimerase domains. It has been suggested that a NADP-binding motif can be found in the N-terminal portion of this domain that may form a Rossman-type fold.

13-331 3.72e-162

fatty acyl CoA reductases (FARs), extended (e) SDRs; SDRs are Rossmann-fold NAD(P)H-binding proteins, many of which may function as fatty acyl CoA reductases (FAR), acting on medium and long chain fatty acids, and have been reported to be involved in diverse processes such as biosynthesis of insect pheromones, plant cuticular wax production, and mammalian wax biosynthesis. In Arabidopsis thaliana, proteins with this particular architecture have also been identified as the MALE STERILITY 2 (MS2) gene product, which is implicated in male gametogenesis. Mutations in MS2 inhibit the synthesis of exine (sporopollenin), rendering plants unable to reduce pollen wall fatty acids to corresponding alcohols. This N-terminal domain shares the catalytic triad (but not the upstream Asn) and characteristic NADP-binding motif of the extended SDR family. Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids. Extended SDRs are a diverse collection of proteins, and include isomerases, epimerases, oxidoreductases, and lyases; they typically have a TGXXGXXG cofactor binding motif. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs. Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

13-333 2.56e-32

extended (e) SDRs, subgroup 1; This family consists of an SDR module of multidomain proteins identified as putative polyketide sythases fatty acid synthases (FAS), and nonribosomal peptide synthases, among others. However, unlike the usual ketoreductase modules of FAS and polyketide synthase, these domains are related to the extended SDRs, and have canonical NAD(P)-binding motifs and an active site tetrad. Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids. Extended SDRs are a diverse collection of proteins, and include isomerases, epimerases, oxidoreductases, and lyases; they typically have a TGXXGXXG cofactor binding motif. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs. Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

Pseudomonas fluorescens MupV-like, extended (e) SDRs; This subgroup of extended SDR family domains have the characteristic active site tetrad and a well-conserved NAD(P)-binding motif. This subgroup is not well characterized, its members are annotated as having a variety of putative functions. One characterized member is Pseudomonas fluorescens MupV a protein involved in the biosynthesis of Mupirocin, a polyketide-derived antibiotic. Extended SDRs are distinct from classical SDRs.

356-447 4.62e-28

C-terminal domain of fatty acyl CoA reductases; C-terminal domain of fatty acyl CoA reductases, a family of SDR-like proteins. SDRs or short-chain dehydrogenases/reductases are Rossmann-fold NAD(P)H-binding proteins. Many proteins in this FAR_C family may function as fatty acyl-CoA reductases (FARs), acting on medium and long chain fatty acids, and have been reported to be involved in diverse processes such as the biosynthesis of insect pheromones, plant cuticular wax production, and mammalian wax biosynthesis. In Arabidopsis thaliana, proteins with this particular architecture have also been identified as the MALE STERILITY 2 (MS2) gene product, which is implicated in male gametogenesis. Mutations in MS2 inhibit the synthesis of exine (sporopollenin), rendering plants unable to reduce pollen wall fatty acids to corresponding alcohols. The function of this C-terminal domain is unclear.

13-230 4.92e-19

thioester reductase domain; This model includes the terminal domain from the fungal alpha aminoadipate reductase enzyme (also known as aminoadipate semialdehyde dehydrogenase) which is involved in the biosynthesis of lysine, as well as the reductase-containing component of the myxochelin biosynthetic gene cluster, MxcG. The mechanism of reduction involves activation of the substrate by adenylation and transfer to a covalently-linked pantetheine cofactor as a thioester. This thioester is then reduced to give an aldehyde (thus releasing the product) and a regenerated pantetheine thiol. (In myxochelin biosynthesis this aldehyde is further reduced to an alcohol or converted to an amine by an aminotransferase.) This is a fundamentally different reaction than beta-ketoreductase domains of polyketide synthases which act at a carbonyl two carbons removed from the thioester and forms an alcohol as a product. This domain is invariably found at the C-terminus of the proteins which contain it (presumably because it results in the release of the product). The majority of hits to this model are non-ribosomal peptide synthetases in which this domain is similarly located proximal to a thiolation domain (pfam00550). In some cases this domain is found at the end of a polyketide synthetase enzyme, but is unlike ketoreductase domains which are found before the thiolase domains. Exceptions to this observed relationship with the thiolase domain include three proteins which consist of stand-alone reductase domains (GP|466833 from M. leprae, GP|435954 from Anabaena and OMNI|NTL02SC1199 from Strep. coelicolor) and one protein (OMNI|NTL01NS2636 from Nostoc) which contains N-terminal homology with a small group of hypothetical proteins but no evidence of a thiolation domain next to the putative reductase domain. Below the noise cutoff to this model are proteins containing more distantly related ketoreductase and dehydratase/epimerase domains. It has been suggested that a NADP-binding motif can be found in the N-terminal portion of this domain that may form a Rossman-type fold.

extended (e) SDRs; Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids. Extended SDRs are a diverse collection of proteins, and include isomerases, epimerases, oxidoreductases, and lyases; they typically have a TGXXGXXG cofactor binding motif. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs. Complex (multidomain) SDRs such as ketoreductase domains of fatty acid synthase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

14-233 2.34e-08

aldehyde reductase, extended (e) SDRs; This subgroup contains aldehyde reductase of the extended SDR-type and related proteins. Aldehyde reductase I (aka carbonyl reductase) is an NADP-binding SDR; it has an NADP-binding motif consensus that is slightly different from the canonical SDR form and lacks the Asn of the extended SDR active site tetrad. Aldehyde reductase I catalyzes the NADP-dependent reduction of ethyl 4-chloro-3-oxobutanoate to ethyl (R)-4-chloro-3-hydroxybutanoate. Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids.

13-291 8.01e-07

3beta-hydroxysteroid dehydrogenases (3b-HSD)-like, extended (e) SDRs; Extended SDR family domains belonging to this subgroup have the characteristic active site tetrad and a fairly well-conserved NAD(P)-binding motif. 3b-HSD catalyzes the NAD-dependent conversion of various steroids, such as pregnenolone to progesterone, or androstenediol to testosterone. This subgroup includes an unusual bifunctional 3b-HSD/C-4 decarboxylase from Arabidopsis thaliana, and Saccharomyces cerevisiae ERG26, a 3b-HSD/C-4 decarboxylase, involved in the synthesis of ergosterol, the major sterol of yeast. It also includes human 3 beta-HSD/HSD3B1 and C(27) 3beta-HSD/ [3beta-hydroxy-delta(5)-C(27)-steroid oxidoreductase; HSD3B7]. C(27) 3beta-HSD/HSD3B7 is a membrane-bound enzyme of the endoplasmic reticulum, that catalyzes the isomerization and oxidation of 7alpha-hydroxylated sterol intermediates, an early step in bile acid biosynthesis. Mutations in the human NSDHL (NAD(P)H steroid dehydrogenase-like protein) cause CHILD syndrome (congenital hemidysplasia with ichthyosiform nevus and limb defects), an X-linked dominant, male-lethal trait. Mutations in the human gene encoding C(27) 3beta-HSD underlie a rare autosomal recessive form of neonatal cholestasis. Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids. Extended SDRs are a diverse collection of proteins, and include isomerases, epimerases, oxidoreductases, and lyases; they typically have a TGXXGXXG cofactor binding motif.

13-233 1.58e-06

human NSDHL (NAD(P)H steroid dehydrogenase-like protein)-like, extended (e) SDRs; This subgroup includes human NSDHL and related proteins. These proteins have the characteristic active site tetrad of extended SDRs, and also have a close match to their NAD(P)-binding motif. Human NSDHL is a 3beta-hydroxysteroid dehydrogenase (3 beta-HSD) which functions in the cholesterol biosynthetic pathway. 3 beta-HSD catalyzes the oxidative conversion of delta 5-3 beta-hydroxysteroids to the delta 4-3-keto configuration; this activity is essential for the biosynthesis of all classes of hormonal steroids. Mutations in the gene encoding NSDHL cause CHILD syndrome (congenital hemidysplasia with ichthyosiform nevus and limb defects), an X-linked dominant, male-lethal trait. This subgroup also includes an unusual bifunctional [3beta-hydroxysteroid dehydrogenase (3b-HSD)/C-4 decarboxylase from Arabidopsis thaliana, and Saccharomyces cerevisiae ERG26, a 3b-HSD/C-4 decarboxylase, involved in the synthesis of ergosterol, the major sterol of yeast. Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids. Extended SDRs are a diverse collection of proteins, and include isomerases, epimerases, oxidoreductases, and lyases; they typically have a TGXXGXXG cofactor binding motif. SDRs are a functionally diverse family of oxidoreductases that have a single domain with a structurally conserved Rossmann fold, an NAD(P)(H)-binding region, and a structurally diverse C-terminal region. Sequence identity between different SDR enzymes is typically in the 15-30% range; they catalyze a wide range of activities including the metabolism of steroids, cofactors, carbohydrates, lipids, aromatic compounds, and amino acids, and act in redox sensing. Classical SDRs have an TGXXX[AG]XG cofactor binding motif and a YXXXK active site motif, with the Tyr residue of the active site motif serving as a critical catalytic residue (Tyr-151, human 15-hydroxyprostaglandin dehydrogenase numbering). In addition to the Tyr and Lys, there is often an upstream Ser and/or an Asn, contributing to the active site; while substrate binding is in the C-terminal region, which determines specificity. The standard reaction mechanism is a 4-pro-S hydride transfer and proton relay involving the conserved Tyr and Lys, a water molecule stabilized by Asn, and nicotinamide. Atypical SDRs generally lack the catalytic residues characteristic of the SDRs, and their glycine-rich NAD(P)-binding motif is often different from the forms normally seen in classical or extended SDRs. Complex (multidomain) SDRs such as ketoreductase domains of fatty acid sythase have a GGXGXXG NAD(P)-binding motif and an altered active site motif (YXXXN). Fungal type ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

human 3beta-HSD (hydroxysteroid dehydrogenase) and HSD3B1(delta 5-delta 4-isomerase)-like, extended (e) SDRs; This extended-SDR subgroup includes human 3 beta-HSD/HSD3B1 and C(27) 3beta-HSD/ [3beta-hydroxy-delta(5)-C(27)-steroid oxidoreductase; HSD3B7], and related proteins. These proteins have the characteristic active site tetrad and NAD(P)-binding motif of extended SDRs. 3 beta-HSD catalyzes the oxidative conversion of delta 5-3 beta-hydroxysteroids to the delta 4-3-keto configuration; this activity is essential for the biosynthesis of all classes of hormonal steroids. C(27) 3beta-HSD is a membrane-bound enzyme of the endoplasmic reticulum, it catalyzes the isomerization and oxidation of 7alpha-hydroxylated sterol intermediates, an early step in bile acid biosynthesis. Mutations in the human gene encoding C(27) 3beta-HSD underlie a rare autosomal recessive form of neonatal cholestasis. Extended SDRs are distinct from classical SDRs.

10-154 9.46e-05

UDP-Glcnac (UDP-linked N-acetylglucosamine) inverting 4,6-dehydratase, extended (e) SDRs; UDP-Glcnac inverting 4,6-dehydratase was identified in Helicobacter pylori as the hexameric flaA1 gene product (FlaA1). FlaA1 is hexameric, possesses UDP-GlcNAc-inverting 4,6-dehydratase activity, and catalyzes the first step in the creation of a pseudaminic acid derivative in protein glycosylation. Although this subgroup has the NADP-binding motif characteristic of extended SDRs, its members tend to have a Met substituted for the active site Tyr found in most SDR families. Extended SDRs are distinct from classical SDRs. In addition to the Rossmann fold (alpha/beta folding pattern with a central beta-sheet) core region typical of all SDRs, extended SDRs have a less conserved C-terminal extension of approximately 100 amino acids.
