Protein

Endoglucanase B

Gene

celB

Organism
Cellvibrio japonicus (strain Ueda107) (Pseudomonas fluorescens subsp. cellulosa)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

This enzyme catalyzes the endohydrolysis of 1,4-beta-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans. EGB is most active against barley beta-glucan, but showed significant activity against amorphous and crystalline cellulose.

Catalytic activityi

Endohydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans.
