Variant of an alpha amylase using same DNA expression vector construction of recombinant cell detergent additive and composition and process to generate a variant of an alpha - amylase.

摘要

The invention relates to a variant of a parent Termamyl-like alpha-amylase, which variant has alpha-amylase activity and exhibits an alteration in at least one of the following properties relative to said parent alpha-amylase: substrate specificity, substrate binding, substrate cleavage pattern, thermal stability, pH/activity profile, pH/stability profile, stability towards oxidation, CaSUP2+/SUP dependency and specific activity.
