IUBMB Enzyme Nomenclature


Accepted name: (4-O-methyl)-D-glucuronate—lignin esterase

Reaction: a 4-O-methyl-D-glucopyranuronate ester + H2O = 4-O-methyl-D-glucuronic acid + an alcohol

Other name(s): glucuronoyl esterase (ambiguous); 4-O-methyl-glucuronoyl methylesterase; glucuronoyl-lignin ester hydrolase

Systematic name: (4-O-methyl)-D-glucuronate—lignin ester hydrolase

Comments: The enzyme occurs in microorganisms and catalyses the cleavage of the ester bonds between glucuronoyl or 4-O-methyl-glucuronoyl groups attached to xylan and aliphatic or aromatic alcohols in lignin polymers.
