xyloglucan + H2O = xyloglucan cellotetraose
n.a.
: The enzyme from TAX-1515 (XghA) is specific for xyloglucan and does not hydrolyse other cell-wall components. It cleaves glycosidic bonds in xyloglucan and produces mostly cellotetraose units of xyloglucan that included hepta- to nonaglycosides of the composition XXXG, XLXG (or XXLG) and XLLG [16207921].
xyloglucan-specific exo-beta-1,4-glucanase
xyloglucan + H2O = XXXG xyloglucan oligosaccharide + XXLG xyloglucan oligosaccharide + XLXG xyloglucan oligosaccharide + XLLG xyloglucan oligosaccharide
-
generic compounds
: 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.

n.a.
: This unbalanced reaction is used for a display in a Glycan Builder-based pathway.
