EC 2.1.1.321     
Accepted name: type III protein arginine methyltransferase
Reaction: S-adenosyl-L-methionine + [protein]-L-arginine = S-adenosyl-L-homocysteine + [protein]-Nω-methyl-L-arginine
Other name(s): PRMT7 (gene name)
Systematic name: S-adenosyl-L-methionine:[protein]-L-arginine N-methyltransferase ([protein]-Nω-methyl-L-arginine-forming)
Comments: Type III protein arginine methyltransferases catalyse the single methylation of one of the terminal nitrogen atoms of the guanidino group in an L-arginine residue within a protein. Unlike type I and type II protein arginine methyltransferases, which also catalyse this reaction, type III enzymes do not methylate the substrate any further. cf. EC 2.1.1.319, type I protein arginine methyltransferase, EC 2.1.1.320, type II protein arginine methyltransferase, and EC 2.1.1.322, type IV protein arginine methyltransferase.
