Abstract
The inventors have developed a method of altering the amino acid sequence of a fungal alpha-amylase to obtain variants, and they have used the method to construct such variants. The variants may be useful for anti-staling in baked products. Accordingly, the invention provides a method of constructing fungal alpha-amylase variants based on a comparison of three-dimensional (3D) structures of the fungal alpha-amylase and a maltogenic alpha-amylase. One or both models includes a substrate. The invention also provides novel fungal alpha-amylase variants.
