In [[enzymology]], a '''xyloglucan-specific exo-beta-1,4-glucanase''' ({{EC number|3.2.1.155}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:xyloglucan + H<sub>2</sub>O <math>\rightleftharpoons</math> xyloglucan oligosaccharides (exohydrolysis of 1,4-beta-D-glucosidic linkages in xyloglucan)

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[xyloglucan]] and [[water|H<sub>2</sub>O]], and its [[product (chemistry)|products]] are [[xyloglucan oligosaccharide]]s ([[exohydrolysis]] of [[1,4-beta-D-glucosidic]] linkages in xyloglucan).

This enzyme belongs to the family of [[hydrolase]]s, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds.  The [[List of enzymes|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'''.
