XH
Systematic name:
[(1→6)-α-D-xylo]-(1→4)-β-D-glucan glucanohydrolase
Reaction
- xyloglucan + H2O = xyloglucan oligosaccharides
Comments:
The enzyme from Aspergillus aculeatus is specific for xyloglucan and does not hydrolyse other cell-wall components. The reaction involves endohydrolysis of 1,4-β-D-glucosidic linkages in xyloglucan with retention of the β-configuration of the glycosyl residues.
