Arabinofuranosidase; Involved in the degradation of xylan and is a key enzyme in the complete degradation of the plant cell wall. It has a specific arabinofuranose-debranching activity on xylan from gramineae. Acts synergistically with the xylanases and binds specifically to xylan. From small arabinoxylo-oligosides (ranging from arabinoxylotriose to arabinoxylohexaose), it liberates arabinose and, after prolonged incubation, the purified enzyme exhibits some xylanolytic activity as well (By similarity); Belongs to the glycosyl hydr olase 62 family.
