CC   -!- FUNCTION: Endo-1,4-beta-xylanase involved in the hydrolysis of
CC       xylan, a major structural heterogeneous polysaccharide found in
CC       plant biomass representing the second most abundant polysaccharide
CC       in the biosphere, after cellulose. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endohydrolysis of (1->4)-beta-D-xylosidic linkages in
CC         xylans.; EC=3.2.1.8;
CC   -!- PATHWAY: Glycan degradation; xylan degradation.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 11 (cellulase G)
CC       family. {ECO:0000305}.
