In enzymology an inositol 3-methyltransferase (EC 2.1.1.39) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + myo-inositol S-adenosyl-L-homocysteine + 1D-3-O-methyl-myo-inositolThus the two substrates of this enzyme are S-adenosyl methionine and myo-inositol whereas its two products are S-adenosylhomocysteine and 1D-3-O-methyl-myo-inositol.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
