Alpha-L-arabinofuranosidase involved in the hydrolysis of xylan, a major structural heterogeneous polysaccharide found in plant biomass representing the second most abundant polysaccharide in the biosphere, after cellulose. Releases L-arabinose from arabinoxylan (By similarity). Hydrolysis of terminal non-reducing alpha-L-arabinofuranoside residues in alpha-L-arabinosides. Belongs to the glycosyl hydrolase 62 family.
