Accepted name: xyloglucan-specific endo-β-1,4-glucanase
Reaction: xyloglucan + H2O = xyloglucan oligosaccharides
Other name(s): XEG; xyloglucan endo-β-1,4-glucanase; xyloglucanase; xyloglucanendohydrolase; XH; 1,4-β-D-glucan glucanohydrolase
Systematic name: [(1→6)-α-D-xylo]-(1→4)-β-D-glucan glucanohydrolase
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.
