label_lc: 4-o-methyl-glucuronoyl methylesterase activity
description: "Catalysis of the reaction: [X]-4-O-methyl-D-glucuronic acid + H2O = [X]-OH + methyl-D-glucuronic acid. This reaction is the hydrolysis of the ester linkage between 4-O-methyl-D-glucuronic acid (MeGlcA) and an alcohol (-OH) group attached to a molecule, denoted here as [X]."
