3.2.1.139 additional information isoform GH115 is able to release 4-O-methylglucuronoxylan from both polymeric 4-O-methylglucuronoxylan and 4-O-methylglucurono-xylo-oligosaccharides. GH115 cleaves 4-O-ethylglucuronoxylan from both internal and non-reducing end xylosyl residues, with the exception of 4-O-methylglucuronate attached to the non-reducing end of a xylotriose oligosaccharide Rasamsonia emersonii ?
