Polysaccharide O-methyltransferase

S-adenosyl-L-methionine + 1,4-alpha-D-glucooligosaccharide $rightleftharpoons$ S-adenosyl-L-homocysteine + oligosaccharide containing 6-methyl-D-glucose units

Thus, the two substrates of this enzyme are S-adenosyl methionine and 1,4-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. The systematic name of this enzyme class is S-adenosyl-L-methionine:1,4-alpha-D-glucan 6-O-methyltransferase. Other names in common use include polysaccharide methyltransferase, and acylpolysacharide 6-methyltransferase.
