In enzymology a rRNA (guanine-N1-)-methyltransferase (EC 2.1.1.51) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + rRNA S-adenosyl-L-homocysteine + rRNA containing N1-methylguanineThus the two substrates of this enzyme are S-adenosyl methionine and rRNA whereas its two products are S-adenosylhomocysteine and rRNA containing N1-methylguanine.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
