What is "cyclomaltodextrinase"

n. (context enzyme English) Any enzyme that catalyzes the hydrolysis of a cyclomaltodextrin to produce a linear maltodextrin

In enzymology, a cyclomaltodextrinase is an enzyme that catalyzes the chemical reaction

cyclomaltodextrin + HO $\rightleftharpoons$ linear maltodextrin

Thus, the two substrates of this enzyme are cyclomaltodextrin and HO, whereas its product is linear maltodextrin.

This enzyme 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. This enzyme participates in starch and sucrose metabolism.
