IntEnz Enzyme Nomenclature
EC 3.2.1.151

Names

Accepted name:
xyloglucan-specific endo-β-1,4-glucanase
Other names:
XEG
xyloglucan endo-β-1,4-glucanase
xyloglucanase
xyloglucanendohydrolase
1,4-β-D-glucan glucanohydrolase
XH
Systematic name:
[(1→6)-α-D-xylo]-(1→4)-β-D-glucan glucanohydrolase

Reaction

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.
