Enzyme Information

2.6.1.83
LL-diaminopimelate aminotransferase.
based on mapping to UniProt O84395
LL-2,6-diaminoheptanedioate + 2-oxoglutarate = (S)-2,3,4,5- tetrahydropyridine-2,6-dicarboxylate + L-glutamate + H(2)O.
-!- 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.
