Type III Pyridoxal 5-phosphate (PLP)-Dependent Enzyme Carboxynorspermidine Decarboxylase; Carboxynorspermidine decarboxylase (CANSDC) catalyzes the decarboxylation of carboxynorspermidine, the last step in the biosynthesis of norspermidine. It is homologous to eukaryotic ornithine decarboxylase (ODC) and diaminopimelate decarboxylase (DapDC), which are fold type III PLP-dependent enzymes that contain an N-terminal PLP-binding TIM-barrel domain and a C-terminal beta-sandwich domain, similar to bacterial alanine racemases. Based on this similarity, CANSDC may require homodimer formation and the presence of the PLP cofactor for its catalytic activity.

Type III Pyridoxal 5-phosphate (PLP)-Dependent Enzymes, Ornithine and Diaminopimelate Decarboxylases, and Related Enzymes; This family includes eukaryotic ornithine decarboxylase (ODC, EC 4.1.1.17), diaminopimelate decarboxylase (DapDC, EC 4.1.1.20), plant and prokaryotic biosynthetic arginine decarboxylase (ADC, EC 4.1.1.19), carboxynorspermidine decarboxylase (CANSDC), and ODC-like enzymes from diverse bacterial species. These proteins are fold type III PLP-dependent enzymes that catalyze essential steps in the biosynthesis of polyamine and lysine. ODC and ADC participate in alternative pathways of the biosynthesis of putrescine, which is the precursor of aliphatic polyamines in many organisms. ODC catalyzes the direct synthesis of putrescine from L-ornithine, while ADC converts L-arginine to agmatine, which is hydrolysed to putrescine by agmatinase in a pathway that exists only in plants and bacteria. DapDC converts meso-2,6-diaminoheptanedioate to L-lysine, which is the final step of lysine biosynthesis. CANSDC catalyzes the decarboxylation of carboxynorspermidine, which is the last step in the synthesis of norspermidine. The PLP-dependent decarboxylases in this family contain an N-terminal PLP-binding TIM-barrel domain and a C-terminal beta-sandwich domain, similar to bacterial alanine racemases. 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. Prokaryotic ornithine, lysine and biodegradative arginine decarboxylases are fold type I PLP-dependent enzymes and are not included in this family.

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.

Type III Pyridoxal 5-phosphate (PLP)-Dependent Enzyme MccE; This subfamily is composed of uncharacterized proteins with similarity to Escherichia coli MccE, a hypothetical protein that is homologous to eukaryotic ornithine decarboxylase (ODC) and diaminopimelate decarboxylase (DapDC). ODC and DapDC are fold type III PLP-dependent enzymes that contain an N-terminal PLP-binding TIM-barrel domain and a C-terminal beta-sandwich domain, similar to bacterial alanine racemases. ODC participates in the formation of putrescine by catalyzing the decarboxylation of ornithine, the first step in polyamine biosynthesis. DapDC participates in the last step of lysine biosynthesis, the conversion of meso-2,6-diaminoheptanedioate to L-lysine. Most members of this subfamily share the same domain architecture as ODC and DapDC. A few members, including Escherichia coli MccE, contain an additional acetyltransferase domain at the C-terminus.

Type III Pyridoxal 5-phosphate (PLP)-Dependent Enzyme Ornithine Decarboxylase; This subfamily is composed mainly of eukaryotic ornithine decarboxylases (ODC, EC 4.1.1.17) and ODC-like enzymes from prokaryotes represented by Vibrio vulnificus LysineOrnithine decarboxylase. These are fold type III PLP-dependent enzymes that differ from most bacterial ODCs which are fold type I PLP-dependent enzymes. ODC participates in the formation of putrescine by catalyzing the decarboxylation of ornithine, the first step in polyamine biosynthesis. Members of this subfamily contain an N-terminal PLP-binding TIM-barrel domain and a C-terminal beta-sandwich domain, similar to bacterial alanine racemases. 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. Homodimer formation and the presence of the PLP cofactor are required for catalytic activity. Also members of this subfamily are proteins with homology to ODC but do not possess any catalytic activity, the Antizyme inhibitor (AZI) and ODC-paralogue (ODC-p). AZI binds to the regulatory protein Antizyme with a higher affinity than ODC and prevents ODC degradation. ODC-p is a novel ODC-like protein, present only in mammals, that is specifically exressed in the brain and testes. ODC-p may function as a tissue-specific antizyme inhibitory protein.
