In enzymology a protein-histidine N-methyltransferase (EC 2.1.1.85) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + protein L-histidine S-adenosyl-L-homocysteine + protein Ntau-methyl-L-histidineThus the two substrates of this enzyme are S-adenosyl methionine and protein L-histidine whereas its two products are S-adenosylhomocysteine and protein Ntau-methyl-L-histidine.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
