FunFam 81307: Probable aspartate aminotransferase 2

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Aspartate transaminase. [EC: 2.6.1.1]
L-aspartate + 2-oxoglutarate = oxaloacetate + L-glutamate.
  • Also acts on L-tyrosine, L-phenylalanine and L-tryptophan.
  • This activity can be formed from EC 2.6.1.57 by controlled proteolysis.

LL-diaminopimelate aminotransferase. [EC: 2.6.1.83]
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.
