| EC Number | 3.2.1.14 |
| Enzyme Function | FUNCTION: Defense against chitin-containing fungal pathogens. Binds the hyphal tips, lateral walls and septa of fungi and degrades mature chitin. {ECO:0000269|PubMed:11826968, ECO:0000269|PubMed:12092848, ECO:0000269|PubMed:14981295, ECO:0000269|PubMed:7763659}. |
| Temperature Dependency | BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Enzyme activity is retained almost fully under 40 degrees Celsius and completely destroyed at 70 degrees Celsius. At 60 degrees Celsius the activity was over 80% compared to the untreated enzyme. {ECO:0000269|PubMed:7763659}; |
| PH Dependency | BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is about 5.0. Stable between pH 4-8. {ECO:0000269|PubMed:7763659}; |
