Functioni

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).By similarity

Catalytic activityi

Hydrolysis of terminal non-reducing alpha-L-arabinofuranoside residues in alpha-L-arabinosides.
