Protein

Probable 1,4-beta-D-glucan cellobiohydrolase C

Gene
cbhC, ACLA_062560
Organism
Aspergillus clavatus (strain ATCC 1007 / CBS 513.65 / DSM 816 / NCTC 3887 / NRRL 1)
Status
Reviewed - Annotation score: 3 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 By similarity.

Catalytic activityi

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

Domaini

Has a modular structure: a carbohydrate-binding module (CBM) at the N-terminus, a linker rich in threonines, and a C-terminal exocellobiohydrolase catalytic module. The genes for catalytic modules and CBMs seem to have evolved separately and have been linked by gene fusion.
