DE   5-guanidino-2-oxopentanoate (3R)-methyltransferase.
AN   2-ketoarginine methyltransferase.
CA   5-guanidino-2-oxopentanoate + S-adenosyl-L-methionine = (3R)-5-guanidino-
CA   3-methyl-2-oxopentanoate + S-adenosyl-L-homocysteine + H(+).
CC   -!- The enzyme is involved in production of the rare amino acid (3R)-3-
CC       methyl-L-arginine.
CC   -!- The compound is used by the epiphytic bacterium Pseudomonas syringae
CC       pv. syringae as an antibiotic against the related pathogenic species
CC       Pseudomonas savastanoi pv. glycinea.
CC   -!- Other bacteria incorporate the compound into more complex compounds
CC       such as the peptidyl nucleoside antibiotic arginomycin.
