'''Acetylxylan esterase''' (AXE) catalyzes the deacetylation of xylans and xylo-oligosaccharides. AXE is involved in the biodegradation of hemicellulose. AXE hydrolyzes the ester linkages of the acetyl groups in position 2 and/or 3 of xylose moiety of naturally acetylated xylan from hardwood. AXE is one of the accessory enzymes which are part of the xylanolytic system. Together with xylanase, β-xylosidase, α-arabinofuranosidase and methylglucoronidase, AXE is required for the complete degradation of xylan. Xylan is the major constituent of hemicellulose which is the second most abundant polysaccharide in plants.

Acetylxylan esterase (AXE) catalyzes the deacetylation of xylans and xylo-oligosaccharides. AXE is involved in the biodegradation of hemicellulose. AXE hydrolyzes the ester linkages of the acetyl groups in position 2 and/or 3 of xylose moiety of naturally acetylated xylan from hardwood. AXE is one of the accessory enzymes which are part of the xylanolytic system. Together with xylanase, β-xylosidase, α-arabinofuranosidase and methylglucoronidase, AXE is required for the complete degradation of xylan.
