Zusammenfassung: | The present invention relates to novel enzyme variants useful in a variety of cleaning compositions, and DNA sequences encoding such enzyme variants.
The present invention relates to Subtilisin DY variants having a modified amino acid sequence of wild-type Subtilisin DY amino acid sequence, the wild-type amino acid sequence comprising a first loop region, a second loop region, a third loop region, a fourth loop region, a fifth loop region and a sixth loop region; wherein the modified amino acid sequence comprises different amino acids than that occurring in wild-type Subtilisin DY (i.e., substitution) at specifically identified positions in one or more of the loop regions whereby the Subtilisin DY variant has decreased adsorption to, and increased hydrolysis of, an insoluble substrate as compared to the wild-type Subtilisin DY. The present invention also relates to DNA sequences encoding such Subtilisin DY variants. The present invention also relates to compositions comprising such Subtilisin DY variants for cleaning a variety of surfaces. |
