2-Ketoarginine methyltransferase (EC 2.1.1.243 mrsA (gene)) is an enzyme with system name S-adenosyl-L-methionine:5-carbamimidamido-2-oxopentanoate S-methyltransferase. This enzyme catalyses the following chemical reaction S-adenosyl-L-methionine + 5-guanidino-2-oxopentanoate S-adenosyl-L-homocysteine + 5-guanidino-3-methyl-2-oxopentanoateThe enzyme is involved in production of the rare amino acid 3-methylarginine.
