2-ketoarginine methyltransferase

UniProtKB accession:  D5FKJ3

Grouped By:  Matching UniProtKB accession

UniProtKB description:  S-adenosyl-L-methionine-dependent methyltransferase involved in the formation of the rare amino acid 3-methylarginine (MeArg), which is used as a potent antibiotic against the closely related soybean pathogen P.syringae pv. glycinea (PubMed:20190091). Transfers the methyl group from S-adenosyl-L-methionine into 5-guanidino-2-oxopentanoate acid to yield 5-guanidino-3-methyl-2-oxopentanoate, a precursor of MeArg (PubMed:20190091).
