CC -!- FUNCTION: Alpha-L-arabinofuranosidase involved in the degradation of
CC arabinoxylan, a major component of plant hemicellulose. Able to
CC hydrolyze 1,5-, 1,3- and 1,2-alpha-linkages not only in L-
CC arabinofuranosyl oligosaccharides, but also in polysaccharides
CC containing terminal non-reducing L-arabinofuranoses in side chains,
CC like L-arabinan, arabinogalactan and arabinoxylan (By similarity).
CC {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 -!- PATHWAY: Glycan metabolism; L-arabinan degradation.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- DOMAIN: Organized into two domains: an N-terminal catalytic domain and
CC a C-terminal arabinose-binding domain (ABD). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 54 family. {ECO:0000305}.
