>TIGR01048 lysA diaminopimelate decarboxylase; InterPro: IPR002986 Pyridoxal-dependent decarboxylases that act on ornithine-, lysine-, arginine- and related substrates can be classified into different families on the basis of sequence similarity , . One of these families includes ornithine decarboxylase (ODC), which catalyses the transformation of ornithine into putrescine; prokaryotic diaminopimelic acid decarboxylase (DAPDC), which catalyses the conversion of diaminopimelic acid into lysine, the final step of lysine biosynthesis; Pseudomonas syringae pv. tabaci protein, tabA, which is probably involved in tabtoxin biosynthesis and is similar to DAPDC; and bacterial and plant biosynthetic arginine decarboxylase (ADC), which catalyses the transformation of arginine into agmatine, the first step in putrescine synthesis from arginine. Although these proteins, which are known collectively as group IV decarboxylases , probably share a common evolutionary origin, their levels of sequence similarity are low, being confined to a few short conserved regions. These conserved motifs suggest a common structural arrangement for positioning of substrate and the cofactor pyridoxal 5'-phosphate among bacterial DAP decarboxylases, eukaryotic ornithine decarboxylases and arginine decarboxylases . The structure of bacterial diaminopimelate decarboxylase has been determined . ; GO: 0008836 diaminopimelate decarboxylase activity, 0009089 lysine biosynthetic process via diaminopimelate.
