| Enzyme Function | FUNCTION: Endo-acting xylanase which specifically cleaves internal linkages on the xylan backbone, releasing xylooligosaccharides. Is also probably able, via its C-terminal domain, to remove acetyl groups from acetylated xylan, and thus it is probably capable of hydrolyzing acetylated xylan. {ECO:0000269|Ref.2}. |
| Temperature Dependency | BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Optimum temperature is 38 degrees Celsius.; |
| PH Dependency | BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 5.6. Active from pH 4.0 to 8.0.; |
| Pathway | PATHWAY: Glycan degradation; xylan degradation. |
