 1-493 0e+00

nitrate reductase, beta subunit; The Nitrate reductase enzyme complex allows bacteria to use nitrate as an electron acceptor during anaerobic growth. The enzyme complex consists of a tetramer that has an alpha, beta and 2 gamma subunits. The alpha and beta subunits have catalytic activity and the gamma subunits attach the enzyme to the membrane and is a b-type cytochrome that receives electrons from the quinone pool and transfers them to the beta subunit. This model is specific for the beta subunit for nitrate reductase I (narH) and nitrate reductase II (narY) for gram positive and gram negative bacteria.A few thermophiles and archaea also match the model.The seed members used in this model are all experimentally characterized and include the following:SP:P11349, and SP:P19318, both E.Coli (NarH and NarY respectively), SP:P42176 from B. Subtilis, GP:11344602 from Psuedomonas fluorescens,GP:541762 from Paracoccus denitrificans, and GP:18413622 from Halomonas halodenitrificans. This model also matches Pfam pfam00037 for 4Fe-4S binding domain. [Energy metabolism, Anaerobic]

 3-367 0e+00

beta subunit of nitrate reductase A (NarH) and similar proteins; This subfamily includes nitrate reductase A, a member of the DMSO reductase family. The respiratory nitrate reductase complex (NarGHI) from E. coli is a heterotrimer, with the catalytic subunit (NarG) with a molybdo-bis (molybdopterin guanine dinucleotide) cofactor and an [Fe-S] cluster, the electron transfer subunit (NarH) with four [Fe-S] clusters, and the integral membrane subunit (NarI) with two b-type hemes. Nitrate reductase A often forms a respiratory chain with the formate dehydrogenase via the lipid soluble quinol pool. Electron transfer from formate to nitrate is coupled to proton translocation across the cytoplasmic membrane generating proton motive force by a redox loop mechanism. Demethylmenaquinol (DMKH2) has been shown to be a good substrate for NarGHI in nitrate respiration in E. coli.

 1-493 0e+00

nitrate reductase, beta subunit; The Nitrate reductase enzyme complex allows bacteria to use nitrate as an electron acceptor during anaerobic growth. The enzyme complex consists of a tetramer that has an alpha, beta and 2 gamma subunits. The alpha and beta subunits have catalytic activity and the gamma subunits attach the enzyme to the membrane and is a b-type cytochrome that receives electrons from the quinone pool and transfers them to the beta subunit. This model is specific for the beta subunit for nitrate reductase I (narH) and nitrate reductase II (narY) for gram positive and gram negative bacteria.A few thermophiles and archaea also match the model.The seed members used in this model are all experimentally characterized and include the following:SP:P11349, and SP:P19318, both E.Coli (NarH and NarY respectively), SP:P42176 from B. Subtilis, GP:11344602 from Psuedomonas fluorescens,GP:541762 from Paracoccus denitrificans, and GP:18413622 from Halomonas halodenitrificans. This model also matches Pfam pfam00037 for 4Fe-4S binding domain. [Energy metabolism, Anaerobic]

 3-367 0e+00

beta subunit of nitrate reductase A (NarH) and similar proteins; This subfamily includes nitrate reductase A, a member of the DMSO reductase family. The respiratory nitrate reductase complex (NarGHI) from E. coli is a heterotrimer, with the catalytic subunit (NarG) with a molybdo-bis (molybdopterin guanine dinucleotide) cofactor and an [Fe-S] cluster, the electron transfer subunit (NarH) with four [Fe-S] clusters, and the integral membrane subunit (NarI) with two b-type hemes. Nitrate reductase A often forms a respiratory chain with the formate dehydrogenase via the lipid soluble quinol pool. Electron transfer from formate to nitrate is coupled to proton translocation across the cytoplasmic membrane generating proton motive force by a redox loop mechanism. Demethylmenaquinol (DMKH2) has been shown to be a good substrate for NarGHI in nitrate respiration in E. coli.

 6-417 1.26e-121

beta subunit of ethylbenzene-dehydrogenase (EBDH); This subfamily includes ethylbenzene dehydrogenase (EBDH, EC 1.17.99.2), a member of the DMSO reductase family. EBDH oxidizes the hydrocarbon ethylbenzene to (S)-1-phenylethanol. It is a heterotrimer, with the alpha subunit containing the catalytic center with a molybdenum held by two molybdopterin-guanine dinucleotides, the beta subunit containing four iron-sulfur clusters (the electron transfer subunit) and the gamma subunit containing a methionine and a lysine as axial heme ligands. During catalysis, electrons produced by substrate oxidation are transferred to a heme in the gamma subunit and then presumably to a separate cytochrome involved in nitrate respiration.

DMSO Reductase (DMSOR) family members have a large, periplasmic molybdenum-containing alpha subunit as well as a small beta FeS subunit, and may also have a small gamma subunit. . The beta subunits of DMSOR contains four Fe4/S4 and/or Fe3/S4 clusters which transfer the electrons from the alpha subunit to a hydrophobic integral membrane protein, presumably a cytochrome containing two b-type heme groups. The reducing equivalents are then transferred to menaquinone, which finally reduces the electron-accepting enzyme system. Nitrate reductase A contains three subunits (the catalytic subunit NarG, the catalytic subunit NarH with four [Fe-S] clusters, and integral membrane subunit NarI) and often forms a respiratory chain with the formate dehydrogenase via the lipid soluble quinol pool. Ethylbenzene dehydrogenase oxidizes the hydrocarbon ethylbenzene to (S)-1-phenylethanol. Selenate reductase catalyzes reduction of selenate to selenite in bacterial species that can obtain energy by respiring anaerobically with selenate as the terminal electron acceptor.

 169-355 2.05e-42

polysulfide reductase beta (PsrB) subunit; This family includes the beta subunit of bacterial polysulfide reductase (PsrABC), an integral membrane-bound enzyme responsible for quinone-coupled reduction of polysulfides, a process important in extreme environments such as deep-sea vents and hot springs. Polysulfide reductase contains three subunits: a catalytic subunit PsrA, an electron transfer PsrB subunit and the hydrophobic transmembrane PsrC subunit. PsrB belongs to the DMSO reductase superfamily that contains [4Fe-4S] clusters which transfer the electrons from the A subunit to the hydrophobic integral membrane C subunit via the B subunit. In Shewanella oneidensis, which has highly diverse anaerobic respiratory pathways, PsrABC is responsible for H2S generation as well as its regulation via respiration of sulfur species. PsrB transfers electrons from PsrC (serving as quinol oxidase) to the catalytic subunit PsrA for reduction of corresponding electron acceptors. It has been shown that T. thermophilus polysulfide reductase could be a key energy-conserving enzyme of the respiratory chain, using polysulfide as the terminal electron acceptor and pumping protons across the membrane.

 170-270 3.81e-38

Beta subunit of the DMSO Reductase (DMSOR) family; This family consists of the small beta iron-sulfur (FeS) subunit of the DMSO Reductase (DMSOR) family. Members of this family also contain a large, periplasmic molybdenum-containing alpha subunit and may have a small gamma subunit as well. Examples of heterodimeric members with alpha and beta subunits include arsenite oxidase, and tungsten-containing formate dehydrogenase (FDH-T) while heterotrimeric members containing alpha, beta, and gamma subunits include formate dehydrogenase-N (FDH-N), and nitrate reductase (NarGHI). The beta subunit contains four Fe4/S4 and/or Fe3/S4 clusters which transfer the electrons from the alpha subunit to a hydrophobic integral membrane protein, presumably a cytochrome containing two b-type heme groups. The reducing equivalents are then transferred to menaquinone, which finally reduces the electron-accepting enzyme system.

Members of this family also contain a large, periplasmic molybdenum-containing alpha subunit and may have a small gamma subunit as well. Examples of heterodimeric members with alpha and beta subunits include arsenite oxidase, and tungsten-containing formate dehydrogenase (FDH-T) while heterotrimeric members containing alpha, beta, and gamma subunits include formate dehydrogenase-N (FDH-N), and nitrate reductase (NarGHI). The beta subunit contains four Fe4/S4 and/or Fe3/S4 clusters which transfer the electrons from the alpha subunit to a hydrophobic integral membrane protein, presumably a cytochrome containing two b-type heme groups. The reducing equivalents are then transferred to menaquinone, which finally reduces the electron-accepting enzyme system.

beta FeS subunits of formate dehydrogenase N (FDH-N) and similar proteins; This family contains beta FeS subunits of several dehydrogenases in the DMSO reductase superfamily, including formate dehydrogenase N (FDH-N), tungsten-containing formate dehydrogenase (W-FDH) and other similar proteins. FDH-N is a major component of nitrate respiration of Escherichia coli; it catalyzes the oxidation of formate to carbon dioxide, donating the electrons to a second substrate to a cytochrome. W-FDH contains a tungsten instead of molybdenum at the catalytic center and seems to be exclusively found in organisms such as hyperthermophilic archaea that live in extreme environments. It catalyzes the oxidation of formate to carbon dioxide, donating the electrons to a second substrate.

the FeS subunit of hydrogenase 2; This subfamily includes the beta-subunit of hydrogenase 2 (Hyd-2), an enzyme that catalyzes the reversible oxidation of H2 to protons and electrons. Hyd-2 is membrane-associated and forms an unusual heterotetrameric [NiFe]-hydrogenase in that it lacks the typical cytochrome b membrane anchor subunit that transfers electrons to the quinone pool. The electron transfer subunit of Hyd-2 (HybA) which is predicted to contain four iron-sulfur clusters, is essential for electron transfer from Hyd-2 to menaquinone/demethylmenaquinone (MQ/DMQ) to couple hydrogen oxidation to fumarate reduction.

uncharacterized subfamily of beta subunit of formate dehydrogenase; This subfamily includes the beta-subunit of formate dehydrogenases that are as yet uncharacterized. Members of the DMSO reductase family include formate dehydrogenase N and O (FDH-N, FDH-O) and tungsten-containing formate dehydrogenase (W-FDH) and other similar proteins. FDH-N, a major component of nitrate respiration of Escherichia coli, is involved in the major anaerobic respiratory pathway in the presence of nitrate, catalyzing the oxidation of formate to carbon dioxide at the expense of nitrate reduction to nitrite. It forms a heterotrimer; the alpha-subunit (FDH-G) is the catalytic site of formate oxidation and membrane-associated, incorporating a selenocysteine (SeCys) residue and a [4Fe/4S] cluster in addition to two bis-MGD cofactors, the beta subunit (FDH-H) contains four [4Fe/4S] clusters which transfer the electrons from the alpha subunit to the gamma-subunit (FDH-I), a hydrophobic integral membrane protein, presumably a cytochrome containing two b-type heme groups. W-FDH contains a tungsten instead of molybdenum at the catalytic center. This enzyme seems to be exclusively found in organisms such as hyperthermophilic archaea that live in extreme environments. It is a heterodimer of a large and a small subunit; the large subunit harbors the W site and one [4Fe-4S] center and the small subunit, containing three [4Fe-4S] clusters, functions to transfer electrons.

N-terminal FeS domain of pyrogallol-phloroglucinol transhydroxylase (TH), beta subunit; This family includes the beta subunit of pyrogallol-phloroglucinol transhydroxylase (TH), a cytoplasmic molybdenum (Mo) enzyme from anaerobic microorganisms like Pelobacter acidigallici and Desulfitobacterium hafniense which catalyzes the conversion of pyrogallol to phloroglucinol, an important building block of plant polymers. TH belongs to the DMSO reductase (DMSOR) family; it is a heterodimer consisting of a large alpha catalytic subunit and a small beta FeS subunit. The beta subunit has two domains with the N-terminal domain containing three [4Fe-4S] centers and a seven-stranded, mainly antiparallel beta-barrel domain. In the anaerobic bacterium Pelobacter acidigallici, gallic acid, pyrogallol, phloroglucinol, or phloroglucinol carboxylic acid are fermented to three molecules of acetate (plus CO2), and TH is the key enzyme in the fermentation pathway, which converts pyrogallol to phloroglucinol in the absence of O2.

In E. coli three formate dehydrogenases are synthesized that are capable of oxidizing formate; Fdh-H, couples formate disproportionation to hydrogen and CO2, and is part of the cytoplasmically oriented formate hydrogenlyase complex, while FDH-N and FDH-O indicate their respective induction after growth with nitrate and oxygen. Little is known about FDH-O, although it shows formate oxidase activity during aerobic growth and is also synthesized during nitrate respiration, similar to FDH-N.

 183-262 7.99e-17

The beta FeS subunit of formate dehydrogenase-N (FDH-N); This subfamily contains beta FeS subunit of formate dehydrogenase-N (FDH-N), a member of the DMSO reductase family. FDH-N is involved in the major anaerobic respiratory pathway in the presence of nitrate, catalyzing the oxidation of formate to carbon dioxide at the expense of nitrate reduction to nitrite. Thus, FDH-N is a major component of nitrate respiration of Escherichia coli. This integral membrane enzyme forms a heterotrimer; the alpha-subunit (FDH-G) is the catalytic site of formate oxidation and membrane-associated, incorporating a selenocysteine (SeCys) residue and a [4Fe/4S] cluster in addition to two bis-MGD cofactors, the beta subunit (FDH-H) contains four [4Fe/4S] clusters which transfer the electrons from the alpha subunit to the gamma-subunit (FDH-I), a hydrophobic integral membrane protein, presumably a cytochrome containing two b-type heme groups.

 179-262 3.64e-13

uncharacterized subfamily of DMSO Reductase beta subunit family; This family consists of the small beta iron-sulfur (FeS) subunit of the DMSO Reductase (DMSOR) family. Members of this family also contain a large, periplasmic molybdenum-containing alpha subunit and may have a small gamma subunit as well. Examples of heterodimeric members with alpha and beta subunits include arsenite oxidase, and tungsten-containing formate dehydrogenase (FDH-T) while heterotrimeric members containing alpha, beta, and gamma subunits include formate dehydrogenase-N (FDH-N), and nitrate reductase (NarGHI). The beta subunit contains four Fe4/S4 and/or Fe3/S4 clusters which transfer the electrons from the alpha subunit to a hydrophobic integral membrane protein, presumably a cytochrome containing two b-type heme groups. The reducing equivalents are then transferred to menaquinone, which finally reduces the electron-accepting enzyme system.

 183-228 2.62e-12

HycB, HydN and similar proteins; This family includes HycB, the FeS subunit of a membrane-associated formate hydrogenlyase system (FHL-1) in Escherichia coli that breaks down formate, produced during anaerobic fermentation, to H2 and CO2. FHL-1 consists of formate dehydrogenase H (FDH-H) and the hydrogenase 3 complex (Hyd-3). HycB is thought to code for the [4Fe-4S] ferredoxin subunit of hydrogenase 3, which functions as an intermediate electron carrier protein between hydrogenase 3 and formate dehydrogenase. HydN codes for the [4Fe-4S] ferredoxin subunit of FDH-H; a hydN in-frame deletion mutation causes only weak reduction in hydrogenase activity, but loss of more than 60% of FDH-H activity. This pathway is only active at low pH and high formate concentrations, and is thought to provide a detoxification/de-acidification system countering the buildup of formate during fermentation.

tungsten-containing formate dehydrogenase, small subunit; This subfamily contains beta subunit of Tungsten-containing formate dehydrogenase (W-FDH), a member of the DMSO reductase family. W-FDH contains a tungsten instead of molybdenum at the catalytic center. This enzyme seems to be exclusively found in organisms such as hyperthermophilic archaea that live in extreme environments. It is a heterodimer of a large and a small subunit; the large subunit harbors the W site and one [4Fe-4S] center and the small subunit, containing three [4Fe-4S] clusters, functions to transfer electrons.

 183-264 4.01e-05

uncharacterized subfamily of DMSO Reductase beta subunit family; This family consists of the small beta iron-sulfur (FeS) subunit of the DMSO Reductase (DMSOR) family. Members of this family also contain a large, periplasmic molybdenum-containing alpha subunit and may have a small gamma subunit as well. Examples of heterodimeric members with alpha and beta subunits include arsenite oxidase, and tungsten-containing formate dehydrogenase (FDH-T) while heterotrimeric members containing alpha, beta, and gamma subunits include formate dehydrogenase-N (FDH-N), and nitrate reductase (NarGHI). The beta subunit contains four Fe4/S4 and/or Fe3/S4 clusters which transfer the electrons from the alpha subunit to a hydrophobic integral membrane protein, presumably a cytochrome containing two b-type heme groups. The reducing equivalents are then transferred to menaquinone, which finally reduces the electron-accepting enzyme system.

 181-227 6.44e-05

Uncharacterized polyferredoxin-like protein; This family contains uncharacterized polyferredoxin protein similar to Methanobacterium thermoautotrophicum MvhB. The mvhB is a gene of the methylviologen-reducing hydrogenase operon. It is predicted to contain 12 [4Fe-4S] clusters, and was therefore suggested to be a polyferredoxin. As a subfamily of the beta subunit of the DMSO Reductase (DMSOR) family, it is predicted to function as electron carrier in the reducing reaction.
