TPP_PYR_E1-PDHc-beta_like cd07036
Pyrimidine (PYR) binding domain of the beta subunits of the E1 components of human pyruvate ...
8-174 2.39e-98

Pyrimidine (PYR) binding domain of the beta subunits of the E1 components of human pyruvate dehydrogenase complex (E1- PDHc) and related proteins; Thiamine pyrophosphate (TPP) family, pyrimidine (PYR) binding domain of the beta subunits of the E1 components of: human pyruvate dehydrogenase complex (E1- PDHc), the acetoin dehydrogenase complex (ADC), and the branched chain alpha-keto acid dehydrogenase/2-oxoisovalerate dehydrogenase complex (BCADC), subfamily. The PYR domain is found in many key metabolic enzymes which use TPP (also known as thiamine diphosphate) as a cofactor. TPP binds in the cleft formed by a PYR domain and a PP domain. The PYR domain, binds the aminopyrimidine ring of TPP, the PP domain binds the diphosphate residue. A polar interaction between the conserved glutamate of the PYR domain and the N1' of the TPP aminopyrimidine ring is shared by most TPP-dependent enzymes, and participates in the activation of TPP. The PYR and PP domains have a common fold, but do not share strong sequence conservation. The PP domain is not included in this sub-family. E1-PDHc is an alpha2beta2 dimer-of-heterodimers having two active sites lying between PYR and PP domains of separate subunits, the PYR domains are arranged on the beta subunit, the PP domains on the alpha subunits. PDHc catalyzes the irreversible oxidative decarboxylation of pyruvate to produce acetyl-CoA in the bridging step between glycolysis and the citric acid cycle. ADC participates in the breakdown of acetoin. BCADC catalyzes the oxidative decarboxylation of 4-methyl-2-oxopentanoate, 3-methyl-2-oxopentanoate and 3-methyl-2-oxobutanoate during the breakdown of branched chain amino acids.

Transketolase, pyrimidine binding domain; Transketolase (TK) catalyzes the reversible transfer ...
54-178 1.37e-38

Transketolase, pyrimidine binding domain; Transketolase (TK) catalyzes the reversible transfer of a two-carbon ketol unit from xylulose 5-phosphate to an aldose receptor, such as ribose 5-phosphate, to form sedoheptulose 7-phosphate and glyceraldehyde 3- phosphate. This enzyme, together with transaldolase, provides a link between the glycolytic and pentose-phosphate pathways. TK requires thiamine pyrophosphate as a cofactor. In most sources where TK has been purified, it is a homodimer of approximately 70 Kd subunits. TK sequences from a variety of eukaryotic and prokaryotic sources show that the enzyme has been evolutionarily conserved. In the peroxisomes of methylotrophic yeast Hansenula polymorpha, there is a highly related enzyme, dihydroxy-acetone synthase (DHAS) (also known as formaldehyde transketolase), which exhibits a very unusual specificity by including formaldehyde amongst its substrates.

8-174 2.39e-98

Pyrimidine (PYR) binding domain of the beta subunits of the E1 components of human pyruvate dehydrogenase complex (E1- PDHc) and related proteins; Thiamine pyrophosphate (TPP) family, pyrimidine (PYR) binding domain of the beta subunits of the E1 components of: human pyruvate dehydrogenase complex (E1- PDHc), the acetoin dehydrogenase complex (ADC), and the branched chain alpha-keto acid dehydrogenase/2-oxoisovalerate dehydrogenase complex (BCADC), subfamily. The PYR domain is found in many key metabolic enzymes which use TPP (also known as thiamine diphosphate) as a cofactor. TPP binds in the cleft formed by a PYR domain and a PP domain. The PYR domain, binds the aminopyrimidine ring of TPP, the PP domain binds the diphosphate residue. A polar interaction between the conserved glutamate of the PYR domain and the N1' of the TPP aminopyrimidine ring is shared by most TPP-dependent enzymes, and participates in the activation of TPP. The PYR and PP domains have a common fold, but do not share strong sequence conservation. The PP domain is not included in this sub-family. E1-PDHc is an alpha2beta2 dimer-of-heterodimers having two active sites lying between PYR and PP domains of separate subunits, the PYR domains are arranged on the beta subunit, the PP domains on the alpha subunits. PDHc catalyzes the irreversible oxidative decarboxylation of pyruvate to produce acetyl-CoA in the bridging step between glycolysis and the citric acid cycle. ADC participates in the breakdown of acetoin. BCADC catalyzes the oxidative decarboxylation of 4-methyl-2-oxopentanoate, 3-methyl-2-oxopentanoate and 3-methyl-2-oxobutanoate during the breakdown of branched chain amino acids.

Transketolase, pyrimidine binding domain; Transketolase (TK) catalyzes the reversible transfer of a two-carbon ketol unit from xylulose 5-phosphate to an aldose receptor, such as ribose 5-phosphate, to form sedoheptulose 7-phosphate and glyceraldehyde 3- phosphate. This enzyme, together with transaldolase, provides a link between the glycolytic and pentose-phosphate pathways. TK requires thiamine pyrophosphate as a cofactor. In most sources where TK has been purified, it is a homodimer of approximately 70 Kd subunits. TK sequences from a variety of eukaryotic and prokaryotic sources show that the enzyme has been evolutionarily conserved. In the peroxisomes of methylotrophic yeast Hansenula polymorpha, there is a highly related enzyme, dihydroxy-acetone synthase (DHAS) (also known as formaldehyde transketolase), which exhibits a very unusual specificity by including formaldehyde amongst its substrates.

Pyrimidine (PYR) binding domain of 1-deoxy-D-xylulose-5-phosphate synthase (DXS), ...
8-168 6.15e-13

Pyrimidine (PYR) binding domain of 1-deoxy-D-xylulose-5-phosphate synthase (DXS), transketolase (TK), and related proteins; Thiamine pyrophosphate (TPP) family, pyrimidine (PYR) binding domain of 1-deoxy-D-xylulose-5-phosphate synthase (DXS), transketolase (TK), and the beta subunits of the E1 component of the human pyruvate dehydrogenase complex (E1- PDHc), subfamily. The PYR domain is found in many key metabolic enzymes which use TPP (also known as thiamine diphosphate) as a cofactor. TPP binds in the cleft formed by a PYR domain and a PP domain. The PYR domain, binds the aminopyrimidine ring of TPP, the PP domain binds the diphosphate residue. A polar interaction between the conserved glutamate of the PYR domain and the N1' of the TPP aminopyrimidine ring is shared by most TPP-dependent enzymes, and participates in the activation of TPP. The PYR and PP domains have a common fold, but do not share strong sequence conservation. The PP domain is not included in this sub-family. Like many TPP-dependent enzymes DXS and TK are homodimers having a PYR and a PP domain on the same subunit. TK has two active sites per dimer which lie between PYR and PP domains of different subunits. For DXS each active site is located at the interface of a PYR and a PP domain from the same subunit. E1-PDHc is an alpha2beta2 dimer-of-heterodimers having two active sites but having the PYR and PP domains arranged on separate subunits, the PYR domains on the beta subunits, the PP domains on the alpha subunits. DXS is a regulatory enzyme of the mevalonate-independent pathway involved in terpenoid biosynthesis, it catalyzes a transketolase-type condensation of pyruvate with D-glyceraldehyde-3-phosphate to form 1-deoxy-D-xylulose-5-phosphate (DXP) and carbon dioxide. TK catalyzes the transfer of a two-carbon unit from ketose phosphates to aldose phosphates. In heterotrophic organisms, TK provides a link between glycolysis and the pentose phosphate pathway and provides precursors for nucleotide, aromatic amino acid and vitamin biosynthesis. TK also plays a central role in the Calvin cycle in plants. PDHc catalyzes the irreversible oxidative decarboxylation of pyruvate to produce acetyl-CoA in the bridging step between glycolysis and the citric acid cycle. This subfamily includes the beta subunits of the E1 component of the acetoin dehydrogenase complex (ADC) and the branched chain alpha-keto acid dehydrogenase/2-oxoisovalerate dehydrogenase complex (BCADC). ADC participates in the breakdown of acetoin. BCADC catalyzes the oxidative decarboxylation of 4-methyl-2-oxopentanoate, 3-methyl-2-oxopentanoate and 3-methyl-2-oxobutanoate during the breakdown of branched chain amino acids.

Pyrimidine (PYR) binding domain of thiamine pyrophosphate (TPP)-dependent enzymes; Thiamine pyrophosphate (TPP) family, pyrimidine (PYR) binding domain; found in many key metabolic enzymes which use TPP (also known as thiamine diphosphate) as a cofactor. TPP binds in the cleft formed by a PYR domain and a PP domain. The PYR domain, binds the aminopyrimidine ring of TPP, the PP domain binds the diphosphate residue. A polar interaction between the conserved glutamate of the PYR domain and the N1' of the TPP aminopyrimidine ring is shared by most TPP-dependent enzymes, and participates in the activation of TPP. The PYR and PP domains have a common fold, but do not share strong sequence conservation. The PP domain is not included in this group. Most TPP-dependent enzymes have the PYR and PP domains on the same subunit although these domains can be alternatively arranged in the primary structure. In the case of 2-oxoisovalerate dehydrogenase (2OXO), sulfopyruvate decarboxylase (ComDE), and the E1 component of human pyruvate dehydrogenase complex (E1- PDHc) the PYR and PP domains appear on different subunits. TPP-dependent enzymes are multisubunit proteins, the smallest catalytic unit being a dimer-of-active sites. For many of these enzymes the active sites lie between PP and PYR domains on different subunits. However, for the homodimeric enzymes 1-deoxy-D-xylulose 5-phosphate synthase (DXS) and Desulfovibrio africanus pyruvate:ferredoxin oxidoreductase (PFOR), each active site lies at the interface of the PYR and PP domains from the same subunit.
