IUBMB Comments

A pyridoxal-phosphate enzyme. In vivo, the reaction occurs in the opposite direction to that shown above. This is one of the final steps in the lysine-biosynthesis pathway of plants (ranging from mosses to flowering plants). meso-Diaminoheptanedioate, an isomer of LL-2,6-diaminoheptanedioate, and the structurally related compounds lysine and ornithine are not substrates. 2-Oxoglutarate cannot be replaced by oxaloacetate or pyruvate. It is not yet known if the substrate of the biosynthetic reaction is the cyclic or acyclic form of tetrahydropyridine-2,6-dicarboxylate.

The expected taxonomic range for this enzyme is: Bacteria, Eukaryota, Archaea

Synonyms
ll-dap-at, atdap-at, l,l-diaminopimelate aminotransferase, ctdap-at, ll-diaminopimelate aminotransferase, diaminopimelate aminotransferase, vsdapl, ct390, ll-dap aminotransferase, sll0480, more
