Activity: Non-reducing end alpha-L-arabinofuranosidase, with EC number 3.2.1.55 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [IABF_CLOTH] Involved in the degradation of arabinan and is a key enzyme in the complete degradation of the plant cell wall. Catalyzes the cleavage of terminal alpha-(1->5)-arabinofuranosyl bonds in small oligosaccharides as alpha-(1->5)-linked arabinobiose/arabinotriose, but does not display significant activity against linear non-substituted arabinan. It is also highly efficient in the cleavage of alpha-(1->3)-linked arabinoside of xylobiose and of the alpha-(1->3)-linked arabinoside decorations of polymeric wheat arabinoxylan. It exhibits very low activity against sugar beet arabinan.
