ID 2.1.1.322 DE type IV protein arginine methyltransferase. CA L-arginyl-[protein] + S-adenosyl-L-methionine = H(+) + N(5)-methyl-L- CA arginyl-[protein] + S-adenosyl-L-homocysteine. CC -!- This enzyme, characterized from the yeast Saccharomyces cerevisiae, CC methylates the the Delta-nitrogen atom of arginine residues within CC proteins. CC -!- Among its substrates are Arg(67) of the ribosomal protein L12. cf. CC EC 2.1.1.319, EC 2.1.1.320 and EC 2.1.1.321. CC -!- Formerly EC 2.1.1.23, EC 2.1.1.124, EC 2.1.1.125 and EC 2.1.1.126. //
