hardwood acetyl glucuronoxylan the target of the enzyme are 2- and 3-monoacetylated xylopyranosyl residues and also the 2,3-di-O-acetylated xylopyranosyl residues. The enzyme does not recognize as a substrate the 3-O-acetyl group on xylopyranosyl residues alpha-1,2-substituted with 4-O-methyl-D-glucuronic acid Orpinomyces sp. ?
