EC Number 2.6.1.83
CAS Registry Number 949001-34-7
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.
Cofactor pyridoxal 5′-phosphate
History
Reactions LL-2,6-diaminoheptanedioate + 2-oxoglutarate = (S)-2,3,4,5- tetrahydropyridine-2,6-dicarboxylate + L-glutamate + H(2)O.
