Accepted name: L-arginine:2-oxoglutarate transaminase
Reaction: L-arginine + 2-oxoglutarate = 5-guanidino-2-oxopentanoate + L-glutamate
Other name(s): argM (gene name); arginine-α-ketoglutarate transaminase
Systematic name: L-arginine:2-oxoglutarate aminotransferase
Comments: Requires pyridoxal 5′-phosphate. The enzyme, characterized from several bacterial species, is known to participate in L-arginine degradation and in the biosynthesis of the rare amino acid (3R)-3-methyl-L-arginine. The enzyme from Streptomyces arginensis also catalyses the activity of EC, L-aspartate:5-guanidino-3-methyl-2-oxopentanoate transaminase.
