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

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

xyloglucan + H₂O $\rightleftharpoons$ 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.

Family 12 was first identified in plant pathogens by discovery in Phytophthora spp.
