In enzymology a glucuronoxylan 4-O-methyltransferase (EC 2.1.1.112) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + glucuronoxylan D-glucuronate S-adenosyl-L-homocysteine + glucuronoxylan 4-O-methyl-D-glucuronateThus the two substrates of this enzyme are S-adenosyl methionine and glucuronoxylan D-glucuronate whereas its two products are S-adenosylhomocysteine and glucuronoxylan 4-O-methyl-D-glucuronate.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
