| catalytic Activity | CATALYTIC ACTIVITY: Reaction=Endohydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans.; EC=3.2.1.4; Evidence={ECO:0000269|PubMed:9335167}; |
| DNA Binding | |
| EC Number | 3.2.1.4 |
| Enzyme Function | FUNCTION: Plays a central role in the recycling of plant biomass. 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 disaccharide 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. |
