2.6.1.126 |
Accepted name: |
L-aspartate:5-guanidino-3-methyl-2-oxopentanoate transaminase |
Reaction: |
L-aspartate + (3R)-5-guanidino-3-methyl-2-oxopentanoate = oxaloacetate + (3R)-3-methyl-L-arginine |
Other name(s): |
argM (gene name); mrsB (gene name) |
Systematic name: |
L-aspartate:5-guanidino-3-methyl-2-oxopentanoate aminotransferase |
Comments: |
Requires pyridoxal 5′-phosphate. The enzyme, characterized from several bacterial species, participates in the biosynthesis of the rare amino acid (3R)-3-methyl-L-arginine. The enzyme from Streptomyces arginensis also catalyses the activity of EC 2.6.1.125, L-arginine:2-oxoglutarate transaminase. |
