Application
| EC Number | Application | Comment | Organism |
|---|---|---|---|
| 3.2.1.8 | additional information | the hybrid xylanase, whose parents are Thermomonospora fusca xylanase A and Aspergillus niger xylanase A, inherits some hydrolytic properties from its parents, and it is an endo-acting xylanase. X4 may be the minimum oligomer hydrolyzed by it | Aspergillus niger |

| 3.2.1.8 | birchwood xylan + H2O | can be hydrolyzed by hybrid xylanase and its Aspergillus parent. Hydrolysis products by hybrid xylanase and its Aspergillus parent are D-xylose, xylobiose, xylotriose, xylotetraose and xylopentaose. Xylotriose is the main product released from birchwood xylan and wheat bran insoluble xylan by hybrid xylanase and its Aspergillus parent, respectively | Aspergillus niger | D-xylose + xylobiose + xylotriose + xylotetraose + xylopentaose + xylohexaose | - |
