General annotation (Comments)

Function

B.fibrisolvens is located in the rumen of ruminant animals, where it contributes to the animal's digestion of plant material by hydrolyzing hemicellulose with its xylanases.

Catalytic activity

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

Pathway

Glycan degradation; xylan degradation.

Sequence similarities

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