CC   -!- FUNCTION: Alpha-L-arabinofuranosidase involved in the hydrolysis of
CC       xylan, a major structural heterogeneous polysaccharide found in plant
CC       biomass representing the second most abundant polysaccharide in the
CC       biosphere, after cellulose. Releases L-arabinose from arabinoxylan (By
CC       similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolysis of terminal non-reducing alpha-L-arabinofuranoside
CC         residues in alpha-L-arabinosides.; EC=3.2.1.55;
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:9000377}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 62 family. {ECO:0000305}.
