GEOBACILLUS STEAROTHERMOPHILUS ALPHA-AMYLASE (AMYS) VARIANTS WITH IMPROVED PROPERTIES

摘要

Described are variants of a parent alpha-amylase that exhibits an alteration 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 dependency, pI, and wash performance. The variants are suitable for starch conversion, ethanol production, laundry washing, dish washing, hard surface cleaning, textile desizing, and/or sweetener production.
