ID 3.2.1.155 DE xyloglucan-specific endo-processive beta-1,4-glucanase. AN [(1->6)-alpha-D-xylo]-(1->4)-beta-D-glucan exo-glucohydrolase. AN xyloglucan-specific exo-beta-1,4-glucanase. CA Hydrolysis of (1->4)-D-glucosidic linkages in xyloglucans so as to CA successively remove oligosaccharides from the newly-formed chain end CA after endo-initiation on a polymer molecule. CC -!- The enzyme removes branched oligosaccharides, containing CC preferentially four glucoside residues in the main chain, from CC xyloglucan molecules in a processive manner after the initial endo- CC type attack on a polysaccharide. CC -!- Hydrolysis occurs at either the unsubstituted D-glucopyranose residue CC in the main backbone and/or the D-glucopyranose residue bearing a CC xylosyl group. CC -!- The enzyme does not display activity, or shows very low activity, CC toward other beta-D-glucans. CC -!- Formerly EC 3.2.1.160. DR Q7Z9M8, XG74_HYPJQ ; //
