CC -!- FUNCTION: Xylan 1,4-beta-xylosidase 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. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of (1->4)-beta-D-xylans, to remove successive D-
CC xylose residues from the non-reducing termini.; EC=3.2.1.37;
CC -!- PATHWAY: Glycan degradation; xylan degradation.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 3 family. {ECO:0000305}.
