Arginine-pyruvate transaminase () is a pyridoxal phosphate-dependent enzyme that catalyzes the chemical reaction
The two substrates of this enzyme characterised from Pseudomonas aeruginosa are L-arginine and pyruvic acid. Its products are 5-guanidino-2-oxopentanoic acid and L-alanine. In this bacterium, the reaction is the first step in a breakdown of the amino acid arginine.
This enzyme is a transferase, specifically a transaminase, which transfer nitrogenous groups. The systematic name of this enzyme class is L-arginine:pyruvate aminotransferase. Other names in common use include arginine:pyruvate transaminase, and AruH.
