XEG;
xyloglucan endo-beta-1,4-glucanase;
xyloglucanase;
xyloglucanendohydrolase;
XH;

Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
BRITE hierarchy
Sysname
[(1->6)-alpha-D-xylo]-(1->4)-beta-D-glucan glucanohydrolase
Reaction(IUBMB)
xyloglucan + H2O = xyloglucan oligosaccharides
Substrate
xyloglucan [CPD:C00807];
H2O [CPD:C00001]
Product
xyloglucan oligosaccharides
Comment
The enzyme from Aspergillus aculeatus is specific for xyloglucan and does not hydrolyse other cell-wall components. The reaction involves endohydrolysis of 1,4-beta-D-glucosidic linkages in xyloglucan with retention of the beta-configuration of the glycosyl residues.
