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.[1][2] The cyclomaltodextrinase is capable of degradation of acarbose to glucose and acarviosine-glucose.[3]
Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1EA9 and 1H3G.
