ID 2.1.1.321 DE type III protein arginine methyltransferase. CA L-arginyl-[protein] + S-adenosyl-L-methionine = H(+) + N(omega)-methyl-L- CA arginyl-[protein] + S-adenosyl-L-homocysteine. CC -!- Type III protein arginine methyltransferases catalyze the single CC methylation of one of the terminal nitrogen atoms of the guanidino CC group in an L-arginine residue within a protein. CC -!- Unlike type I and type II protein arginine methyltransferases, which CC also catalyze this reaction, type III enzymes do not methylate the CC substrate any further. cf. EC 2.1.1.319, EC 2.1.1.320 and CC EC 2.1.1.322. CC -!- Formerly EC 2.1.1.23, EC 2.1.1.124, EC 2.1.1.125 and EC 2.1.1.126.
