ABSTRACT:
The present invention relates to pullulanase variants, wherein the variants have improved properties, for example, altered pH optimum, improved thermostability, altered substrate specificity, increased specific activity or altered cleavage pattern. The present invention also relates to methods of making pullulanase variants having at least one altered property based on the three-dimensional structure of a parent pullulanase.
