Abstract

The inventors have discovered some striking, and not previously predicted structural similarities and differences between the structure of Novamyl and the reported structures of CGTases, and based on this they have constructed variants of maltogenic alpha-amylase having CGTase activity and variants of CGTase having maltogenic alpha-amylase activity. Further, on the basis of sequence homology between Novamyl® and CGTases, the inventors have constructed hybrid enzymes with one or more improvements to specific properties of the parent enzymes, using recombinant DNA methodology.
