Endohydrolysis of (1->4)-beta-D-xylosidic linkages in xylans.

Pathway

Glycan degradation; xylan degradation.

Subcellular location

Secreted By similarity Ref.1.

Sequence similarities

Belongs to the glycosyl hydrolase 11 (cellulase G) family.

Biophysicochemical properties

pH dependence:

Optimum pH is 3.5. Ref.1
