Pyridoxal 5-phosphate (PLP)-binding TIM barrel domain of Type III PLP-Dependent Enzymes, Eukaryotic YBL036c-like proteins; This subfamily contains mostly uncharacterized eukaryotic proteins with similarity to the yeast hypothetical protein YBL036c, which is homologous to a Pseudomonas aeruginosa gene that is co-transcribed with a known proline biosynthetic gene. YBL036c is a single domain monomeric protein with a typical TIM barrel fold. It binds the PLP cofactor and has been shown to exhibit amino acid racemase activity. The YBL036c structure is similar to the N-terminal domain of the fold type III PLP-dependent enzymes, bacterial alanine racemase and eukaryotic ornithine decarboxylase, which are two-domain dimeric proteins. The lack of a second domain in YBL036c may explain limited D- to L-alanine racemase or non-specific racemase activity. Some members of this subfamily are also referred to as PROSC (Proline synthetase co-transcribed bacterial homolog).

Type III Pyridoxal 5-phosphate (PLP)-Dependent Enzymes, YBL036c-like proteins; This family contains mostly uncharacterized proteins, widely distributed among eukaryotes, bacteria and archaea, that bear similarity to the yeast hypothetical protein YBL036c, which is homologous to a Pseudomonas aeruginosa gene that is co-transcribed with a known proline biosynthetic gene.

Pyridoxal 5-phosphate (PLP)-binding TIM barrel domain of Type III PLP-Dependent Enzymes, Yggs-like proteins; This subfamily contains mainly uncharacterized proteobacterial proteins with similarity to the hypothetical Escherichia coli protein YggS, a homolog of yeast YBL036c, which is homologous to a Pseudomonas aeruginosa gene that is co-transcribed with a known proline biosynthetic gene. Like yeast YBL036c, Yggs is a single domain monomeric protein with a typical TIM-barrel fold. Its structure, which shows a covalently-bound PLP cofactor, is similar to the N-terminal domain of the fold type III PLP-dependent enzymes, bacterial alanine racemase and eukaryotic ornithine decarboxylase, which are two-domain dimeric proteins. YggS has not been characterized extensively and its biological function is still unkonwn.

Type III Pyridoxal 5-phosphate (PLP)-Dependent Enzymes; The fold type III PLP-dependent enzyme family is predominantly composed of two-domain proteins with similarity to bacterial alanine racemases (AR) including eukaryotic ornithine decarboxylases (ODC), prokaryotic diaminopimelate decarboxylases (DapDC), biosynthetic arginine decarboxylases (ADC), carboxynorspermidine decarboxylases (CANSDC), and similar proteins. AR-like proteins contain an N-terminal PLP-binding TIM-barrel domain and a C-terminal beta-sandwich domain. They exist as homodimers with active sites that lie at the interface between the TIM barrel domain of one subunit and the beta-sandwich domain of the other subunit. These proteins play important roles in the biosynthesis of amino acids and polyamine. The family also includes the single-domain YBL036c-like proteins, which contain a single PLP-binding TIM-barrel domain without any N- or C-terminal extensions. Due to the lack of a second domain, these proteins may possess only limited D- to L-alanine racemase activity or non-specific racemase activity.

Type III Pyridoxal 5-phosphate (PLP)-Dependent Enzyme Diaminopimelate Decarboxylase; Diaminopimelate decarboxylase (DapDC, EC 4.1.1.20) participates in the last step of lysine biosynthesis. It converts meso-2,6-diaminoheptanedioate to L-lysine. It is a fold type III PLP-dependent enzyme that contains an N-terminal PLP-binding TIM-barrel domain and a C-terminal beta-sandwich domain, similar to bacterial alanine racemases. DapDC exists as homodimers with active sites that lie at the interface between the TIM barrel domain of one subunit and the beta-sandwich domain of the other subunit. Homodimer formation and the presence of the PLP cofactor are required for catalytic activity.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
