SUBTILASE VARIANTS AND COMPOSITIONS

摘要

PURPOSE: Provided are novel mutant protease enzymes or enzyme variants useful in formulating detergent compositions and exhibiting improved wash performance in detergents; cleaning and detergent compositions containing the enzymes; mutated genes coding for the expression of the enzymes when inserted into a suitable host cell or organism; and such host cells transformed therewith and capable of expressing the enzyme variants. CONSTITUTION: Enzymes are produced by mutating the genes for a number of subtilases at positions 167 and 170 and expressing the mutated genes in suitable hosts. The enzymes exhibit improved wash performance in any detergent in comparison to their wild type parent enzymes.
