In enzymology a polysaccharide O-methyltransferase (EC 2.1.1.18) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + 14-alpha-D-glucooligosaccharide S-adenosyl-L-homocysteine + oligosaccharide containing 6-methyl-D-glucose unitsThus the two substrates of this enzyme are S-adenosyl methionine and 14-alpha-D-glucooligosaccharide whereas its two products are S-adenosylhomocysteine and oligosaccharide containing 6-methyl-D-glucose units.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
