EC 2.1.1.322

Accepted name: type IV protein arginine methyltransferase

Reaction: S-adenosyl-L-methionine + [protein]-L-arginine = S-adenosyl-L-homocysteine + [protein]-N5-methyl-L-arginine

Other name(s): RMT2 (gene name)

Systematic name: S-adenosyl-L-methionine:[protein]-L-arginine N-methyltransferase ([protein]-N5-methyl-L-arginine-forming)

Comments: This enzyme, characterized from the yeast Saccharomyces cerevisiae, methylates the the δ-nitrogen atom of arginine residues within proteins. Among its substrates are Arg67 of the ribosomal protein L12. cf. EC 2.1.1.319, type I protein arginine methyltransferase, EC 2.1.1.320, type II protein arginine methyltransferase, and EC 2.1.1.321, type III protein arginine methyltransferase.
