MUTANT alpha -AMYLASE, DETERGENT, DISH WASHING AGENT, AND LIQUEFACTION AGENT

摘要

In the mutant alpha -amylase one or more of the methionine amino acid residues is exchanged with any amino acid residue except for Cys and Met. The thus produced mutant alpha -amylase exhibits an improved stability in the presence of oxidizing agents and an improved thermoactivity at moderate low pH values. The mutant alpha -a amylase is well suited as an additive to detergents, dish washing agents and liquefaction agents.
