Xyloglucan-specific endo-beta-1,4-glucanase

In enzymology, a xyloglucan-specific endo-beta-1,4-glucanase (EC number|3.2.1.151) is an enzyme that catalyzes the chemical reaction

:xyloglucan + H₂O $ightleftharpoons$ xyloglucan oligosaccharides

Thus, the two substrates of this enzyme are xyloglucan and H₂O, whereas its product is xyloglucan oligosaccharides.

This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is [(1->6)-alpha-D-xylo] -(1->4)-beta-D-glucan glucanohydrolase. Other names in common use include XEG, xyloglucan endo-beta-1,4-glucanase, xyloglucanase, xyloglucanendohydrolase, XH, and 1,4-beta-D-glucan glucanohydrolase.
