| 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; |
| DNA Binding | |
| EC Number | 3.2.1.4 |
| Enzyme Function | FUNCTION: Hydrolyzes barley beta-glucan, lichenan, carboxymethylcellulose and xylan. It shows preferential activity against the larger cellooligosaccharides (cellohexaose and cellopentaose); cellotetraose is the smallest substrate degraded completely. |
