ENZYME entry: EC

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