Exo-(1-4)-α-D-glucan lyase

The enzyme exo-(1→4)-α- D -glucan lyase (, α-(1→4)-glucan 1,5-anhydro- D -fructose eliminase, α-1,4-glucan exo-lyase, α-1,4-glucan lyase, GLase) is an enzyme with systematic name (1→4)-α- D -glucan exo-4-lyase (1,5-anhydro- D -fructose-forming). This enzyme catalyses the following chemical reaction


 * linear α-glucan = (n-1) 1,5-anhydro- D -fructose + D -glucose

The enzyme catalyses the sequential degradation of (1→4)-α- D -glucans from the non-reducing end.
