CC   -!- FUNCTION: Endo-1,4-beta-xylanase involved in the hydrolysis of xylan, a
CC       major structural heterogeneous polysaccharide found in plant biomass
CC       representing the second most abundant polysaccharide in the biosphere,
CC       after cellulose. {ECO:0000250}.
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 {ECO:0000250}.
CC   -!- INDUCTION: Expressed in presence of xylan and repressed by glucose.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 10 (cellulase F) family.
CC       {ECO:0000305}.
