?
3.1.1.72 hardwood acetyl glucuronoxylan the enzyme can act on di-O-acetylated Xylp residues, but may have different activities towards the O-2- and O-3-linked acetyl groups, since the content of monoacetylated Xylp units is high after enzyme action. Mode of action, substrate specifiicity, and role of the family CE5 enzyme during deacetylation of soluble natural substrates, i.e. neutral and acidic O-acetylated xylooligosac-charides, overview Trichoderma reesei ?
