An evolution-based designing and characterization of mutants of cyclomaltodextrinase: Molecular modeling and spectroscopic studies.

Cyclomaltodextrinase (CDase) is a member of the alpha-amylase family GH13, the subfamily GH13_20. In addition to CDase and neopullulanase, this subfamily also contains maltogenic amylase. They have common structural features, but different substrate specificity.
