General annotation (Comments)

Function

Endo-1,4-beta-xylanase involved in the hydrolysis of xylan, a major structural heterogeneous polysaccharide found in plant biomass representing the second most abundant polysaccharide in the biosphere, after cellulose By similarity.

Catalytic activity

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

Pathway

Glycan degradation; xylan degradation.

Subcellular location

Secreted By similarity.

Induction

Expressed in presence of xylan and repressed by glucose.

Sequence similarities

Belongs to the glycosyl hydrolase 10 (cellulase F) family.
