| EC Number | 3.2.1.91 |
| Enzyme Function | FUNCTION: Exoglucanase that plays an important function in biomass degradation by catalyzing the hydrolysis of the non-reducing end beta-1,4-glucosidic linkages in cellulose and cellotetraose to release cellobiose. Hydrolyzes crystalline and amorphous cellulose but is inactive on hydroxyethyl cellulose, mannan, galactomannan, xyloglucan, arabinoxylan, arabinan, xylan, and pectin. {ECO:0000269|PubMed:23645193}. |
