additional information Chrysosporium lucknowense acetyl xylan esterase Axe2 is able to hydrolyze acetyl groups both from simple acetylated xylo-oligosaccharides and complex non-soluble acetylglucuronoxylan. Axe2 has a clear preference for acetylated xylo-oligosaccharides with a high degree of substitution. For Axe2 the size of the oligomer is irrelevant. Even though there is difference in substrate affinity towards acetylated xylooligosaccharides from Eucalyptus wood, the final hydrolysis products are the same for Axe2 and Axe3: xylo-oligosaccharides containing one acetyl group located at the non-reducing xylose residue that remains, overview ?

additional information Chrysosporium lucknowense acetyl xylan esterase Axe3 is able to hydrolyze acetyl groups both from simple acetylated xylo-oligosaccharides and complex non-soluble acetylglucuronoxylan. Axe3 shows no preference for acetylated xylo-oligosaccharides with a high degree of substitution. Axe3 has a preference for large acetylated xylo-oligosaccharides when compared to smaller acetylated xylo-oligosaccharides. Even though there is difference in substrate affinity towards acetylated xylooligosaccharides from Eucalyptus wood, the final hydrolysis products are the same for Axe2 and Axe3: xylo-oligosaccharides containing one acetyl group located at the non-reducing xylose residue that remains, overview ?
