α‐Amylases and approaches leading to their enhanced stability

Abstract
The recent state of the knowledge of properties and structure of α-amylases is reviewed with the aim of elucidation the basis for their stabilization. Three principal ways for obtaining stable α-amylases (isolation of enzymes from extremophiles, production of extremophilic enzymes in mesophiles, and modification of mesophilic enzymes) are discussed separately. Detailed experimental examples are given for modification approaches.
