alpha amylases (amys) variants of geobacillus stearothermophilus with improved properties The present invention relates to variants of a parent alpha-amylase which exhibit a change in at least one of the following properties relative to said parent alpha-amylase: specific activity, substrate specificity, substrate binding, substrate cleavage, thermal stability, ph dependent activity, ph dependent stability, oxidative stability, calcium dependence, pl and wash performance. The variants are suitable for starch conversion, ethanol production, laundry, dishwashing, hard surface cleaning, textile degumming and / or sweetener production. |
