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.

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.

Type III Pyridoxal 5-phosphate (PLP)-Dependent Enzyme Bifunctional Aspartate Kinase/Diaminopimelate Decarboxylase; Bifunctional aspartate kinase/diaminopimelate decarboxylase (AspK/DapDC, EC 4.1.1.20/EC 2.7.2.4) typically exists in bacteria. These proteins contain an N-terminal AspK region and a C-terminal DapDC region, which contains a PLP-binding TIM-barrel domain followed by beta-sandwich domain, characteristic of fold type III PLP-dependent enzymes. Members of this subfamily have not been fully characterized. Based on their sequence, these proteins may catalyze both reactions catalyzed by AspK and DapDC. AspK catalyzes the phosphorylation of L-aspartate to produce 4-phospho-L-aspartate while DapDC participates in the last step of lysine biosynthesis, the conversion of meso-2,6-diaminoheptanedioate to L-lysine.

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 Ornithine Decarboxylase-like Antizyme Inhibitor; Antizyme inhibitor (AZI) is homologous to the fold type III PLP-dependent enzyme ODC but does not retain any decarboxylase activity. Like ODC, AZI is presumed to exist as a homodimer. Antizyme is a regulatory protein that binds directly to the ODC monomer to block its active site, leading to its degradation by the 26S proteasome. AZI binds to Antizyme with a higher affinity than ODC, preventing the formation of the Antizyme-ODC complex. Thus, AZI blocks the ability of Antizyme to promote ODC degradation, which leads to increased ODC enzymatic activity and polyamine levels. AZI also prevents the degradation of other proteins regulated by Antizyme, such as cyclin D1.

Type III Pyridoxal 5-phosphate (PLP)-Dependent Enzyme D-Threonine Aldolase; D-threonine aldolase (D-TA, EC 4.3.1.18) reversibly catalyzes the aldol cleavage of D-threonine into glycine and acetaldehyde, and the synthesis of D-threonine from glycine and acetaldehyde. Its activity is present in several genera of bacteria but not in fungi. It requires PLP and a divalent cation such as Co2+, Ni2+, Mn2+, or Mg2+ as cofactors for catalytic activity and thermal stability. Members of this subfamily show similarity to bacterial alanine racemase (AR), a fold type III PLP-dependent enzyme which contains an N-terminal PLP-binding TIM-barrel domain and a C-terminal beta-sandwich domain. AR 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. Based on its similarity to AR, it is possible that low specificity D-TAs also form dimers in solution. Experimental data show that the monomeric form of low specificity D-TAs exhibit full catalytic activity.
