发明名称 STARCH DEBRANCHING ENZYMES
摘要 The invention relates to a genetically engineered variant of a parent starch debranching enzyme, i.e. a pullulanase or an isamylase, 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.
