CC -!- FUNCTION: Contributes to hydrolyze hemicellulose, the major component
CC of plant cell-walls. XLNA and XLNB seem to act sequentially on the
CC substrate to yield xylobiose and xylose as carbon sources.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endohydrolysis of (1->4)-beta-D-xylosidic linkages in xylans.;
CC EC=3.2.1.8;
CC -!- PATHWAY: Glycan degradation; xylan degradation.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 10 (cellulase F) family.
CC {ECO:0000305}.
