In enzymology, a 2,5-diaminovalerate transaminase (EC 2.6.1.8) was a putative enzyme that would have catalyzed the chemical reaction

2,5-diaminopentanoate + 2-oxoglutarate 5-amino-2-oxopentanoate + L-glutamate

Thus, the two substrates of this enzyme would have been 2,5-diaminopentanoate and 2-oxoglutarate, whereas its two products would have been 5-amino-2-oxopentanoate and L-glutamate.[1] The reaction however most likely does not happen. [2]

It was thought to use one cofactor, pyridoxal phosphate.

Nomenclature

The enzyme would have belonged to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is 2,5-diaminopentanoate:2-oxoglutarate aminotransferase. Other names in common use include diamino-acid transaminase, and diamino acid aminotransferase.
