Degrades acetylated xylans by cleaving acetyl side groups from the hetero-xylan backbone. Deacetylation of xylans and xylo-oligosaccharides. Optimum pH is 6. Optimum temperature is 60 degrees Celsius. Glycan degradation; xylan degradation. Monomer. Induced by xylan and repressed by glucose. Expressed at neutral pH, but not under alkaline or acidic condtions. Belongs to the cutinase family. Acetylxylan esterase subfamily.
