Has xylanase activity. Seems to be involved in the release of sugars from the hemicellulolytic fraction in the compost. Endohydrolysis of (1->4)-beta-D-xylosidic linkages in xylans. Glycan degradation; xylan degradation. Repressed on glucose. Belongs to the glycosyl hydrolase 10 (cellulase F) family.
