In enzymology, a xyloglucan-specific exo-beta-1,4-glucanase (EC 3.2.1.155) is an enzyme that catalyzes the chemical reaction
- xyloglucan + H2O [math]\displaystyle{ \rightleftharpoons }[/math] xyloglucan oligosaccharides (exohydrolysis of 1,4-beta-D-glucosidic linkages in xyloglucan)
Thus, the two substrates of this enzyme are xyloglucan and H2O, and its products are xyloglucan oligosaccharides (exohydrolysis of 1,4-beta-D-glucosidic linkages in xyloglucan).
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 exo-glucohydrolase. This enzyme is also called Cel74A.
