Protein

Exoglucanase 1

Gene

cbh1

Organism
Trichoderma koningii (Hypocrea koningii)
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi

Functioni

The biological conversion of cellulose to glucose generally requires three types of hydrolytic enzymes: (1) Endoglucanases which cut internal beta-1,4-glucosidic bonds; (2) Exocellobiohydrolases that cut the dissaccharide cellobiose from the non-reducing end of the cellulose polymer chain; (3) Beta-1,4-glucosidases which hydrolyze the cellobiose and other short cello-oligosaccharides to glucose.

Catalytic activityi

Hydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose and cellotetraose, releasing cellobiose from the non-reducing ends of the chains.
