Cyclomaltodextrinase

The enzyme cyclomaltodextrinase  catalyzes the chemical reaction


 * cyclomaltodextrin + H2O $$\rightleftharpoons$$ linear maltodextrin

It belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is cyclomaltodextrin dextrin-hydrolase (decyclizing). Other names in common use include cycloheptaglucanase, cyclohexaglucanase, and cyclodextrinase. The enzyme participates in starch and sucrose metabolism and acarbose degradation. The cyclomaltodextrinase is capable of degradation of acarbose to glucose and acarviosine-glucose.

Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and.
