In enzymology a mRNA (2′-O-methyladenosine-N6-)-methyltransferase (EC 2.1.1.62) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + m7G(5′)pppAm S-adenosyl-L-homocysteine + m7G(5′)pppm6Am (mRNA containing an N62′-O-dimethyladenosine cap)Thus the two substrates of this enzyme are S-adenosyl methionine and m7G(5′)pppAm whereas its two products are S-adenosylhomocysteine and m7G(5′)pppm6Am (mRNA containing an N62′-O-dimethyladenosine cap).This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
