Alpha-L-arabinofuranosidase B, catalytic
Members of this family, which are present in fungal alpha-L-arabinofuranosidase B, adopt a beta-sandwich fold similar to that of Concanavalin A-like lectins/glucanase. The beta-sandwich fold consists of two anti-parallel beta-sheets with seven and and six strands, respectively. In addition, there are four helices outside of the beta-strands. The beta-sandwich strands are closely packed and curved with a jelly roll topology, creating a small catalytic pocket. The domain catalyzes the hydrolyzis of alpha-1,2-, alpha-1,3- and alpha-1,5-L-arabinofuranosidic bonds in L-arabinose-containing hemicelluloses such as arabinoxylan and L-arabinan.
