The invention relates to a genetically engineered variant of a parent starch debranching enzyme, i.e. a pullulanase or an isoamylase, the enzyme variant having an improved thermostability at a pH in the range of 4-6 compared to the parent enzyme and/or an increased activity towards amylopectin and/or glycogen compared to the parent enzyme, to methods for producing such starch debranching enzyme variants with improved thermostability and/or altered substrate specificity, and to a method for converting starch to one or more sugars using at least one such enzyme variant.

Starch debranching enzymes

The invention relates to a variant of a parent Fungamyl-like fungal alpha-amylase, which exhibits improved thermal stability at acidic pH suitable for, e.g., starch processes.

Fungamyl-like alpha-amylase variants

The present invention relates to a method of constructing a variant of a parent Termamyl-like &#x3b1;-amylase, which variant has &#x3b1;-amylase activity and at least one altered property as compared to the parent &#x3b1;-amylase, comprises

&#x3b1;-amylase mutants
