The two substrates of this enzyme characterised from Pseudomonas bacteria are δ-aminovaleric acid and α-ketoglutaric acid. Its products are 5-oxopentanoic acid and L-glutamic acid.[1]

This enzyme is a transferase, specifically a transaminase, which transfer nitrogenous groups. The systematic name of this enzyme class is 5-aminopentanoate:2-oxoglutarate aminotransferase. Other names in common use include 5-aminovalerate aminotransferase, delta-aminovalerate aminotransferase, and delta-aminovalerate transaminase. It participates in lysine degradation.[2]
