Thus, the two substrates of this enzyme are 2,5-diaminopentanoate and 2-oxoglutarate, whereas its two products are 5-amino-2-oxopentanoate and L-glutamate.
It employs one cofactor, pyridoxal phosphate.
Nomenclature
This enzyme belongs 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.
