label_lc: protein-glutamate o-methyltransferase activity
description: "Catalysis of the reaction: S-adenosyl-L-methionine + protein L-glutamate = S-adenosyl-L-homocysteine + protein L-glutamate 5-methyl ester; this reaction is the methylation of peptidyl-L-glutamate to form peptidyl-L-glutamate 5-methyl ester."
