| BioCyc:3.2.1.151-RXN | Xyloglucan + ∞ WATER --> ∞ Xyloglucan-oligosaccharides | |
| BioCyc:RXN-12401 | Xyloglucan + ∞ WATER --> ∞ CPD-13418 + ∞ CPD-13417 + ∞ CPD-13377 | This enzyme catalyzes the hydrolysis of (1→4)-D-glucosidic linkages in xyloglucans so as to successively remove oligosaccharides from the chain end.The enzyme removes XXXG heptasaccharides, XXLG/XLXG octasaccharides and XLLG nonasaccharides from the end of tamarind seed xyloglucan polymers in a processive manner. Hydrolysis occurs at the unsubstituted D-glucopyranose residue in the main backbone. It is not known whether the cleavage takes place at the reducing or non-reducing end of the polymer. Very low activity with ?-D-glucans. The enzyme from Chrysosporium lucknowense shifts to an endoglucanase mode when acting on linear substrates without bulky substituents on the polymeric backbone such as barley ?-glucan. |
