Abstract
The present invention relates to subtilisin Carlsberg variants having a modified amino acid sequence of wild-type subtilisin Carlsberg 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 Carlsberg (i.e., substitution) at specifically identified positions in one or more of the loop regions whereby the subtilisin Carlsberg variant has decreased adsorption to, and increased hydrolysis of, an insoluble substrate as compared to the wild-type subtilisin Carlsberg. The present invention also relates to the genes encoding such subtilisin Carlsberg variants. The present invention also relates to compositions comprising such subtilisin Carlsberg variants for cleaning a variety of surfaces.
