Abstract:
A cleaning composition comprising:(a) from about 0.0001% to about 10% by weight of the cleaning composition of a protease enzyme which is a carbonyl hydrolase variant having an amino acid sequence not found in nature, which is derived from a precursor carbonyl hydrolase consisting of a substitution of a different amino acid for a plurality of amino acid residues at a position in said precursor carbonyl hydrolase equivalent to position +76 in Bacillus amyloliquefaciens subtilisin, in combination with one or more amino acid residue positions equivalent to those selected from the group consisting of +99, +101, +103, +104, +107, +123, +27, +105, +109, +126, +128, +135, +156, +166, +195, +197, +204, +206, +210, +216, +217, +218, +222 +260, +265, and/or +274 in Bacillus amyloliquefaciens subtilisin, provided that:1) when said carbonyl hydrolase variant includes a substitution of amino acid residues at positions equivalent to +76 and +195, there is also a substitution of an amino acid residue at one or more amino acid residue positions other than amino acid residue positions equivalent to position +99;2) when said carbonyl hydrolase variant includes a substitution of amino acid residues at positions equivalent to +76 and +156, there is also a substitution of an amino acid residue at one or more amino acid residue positions other than amino acid residue positions equivalent to position +99;3) when said carbonyl hydrolase variant includes a substitution of amino acid residues at positions equivalent to +76 and +99, then said carbonyl hydrolase variant only includes substitutions at positions equivalent to +76 and +99, or there is also a substitution of an amino acid residue at one or more amino acid residue positions equivalent to +104, +27, +105, +109, +126, +128, +135, +166, +197, +204, +206, +210, +216, +217, +218, +222, +260, +265, and/or +274;4) when said carbonyl hydrolase variant includes a substitution of amino acid residues at positions equivalent to +76 and +218, then said carbonyl hydrolase variant only includes substitutions at positions equivalent to +76 and +218, or there is also a substitution of an amino acid residue at one or more amino acid residue positions other than amino acid residue positions equivalent to positions +206 and +217;5) when said carbonyl hydrolase variant includes a substitution of amino acid residues at positions equivalent to +76 and +217, then said carbonyl hydrolase variant only includes substitutions at positions equivalent to +76 and +217, or there is also a substitution of an amino acid residue at one or more amino acid residue positions other than amino acid residue positions equivalent to positions +206 and +218;6) when said carbonyl hydrolase variant includes a substitution of amino acid residues at positions equivalent to +76 and +206, then said carbonyl hydrolase variant only includes substitutions at positions equivalent to +76 and +206, or there is also a substitution of an amino acid residue at one or more amino acid residue positions other than amino acid residue positions equivalent to positions +217 and +218; and7) when said carbonyl hydrolase variant includes a substitution of amino acid residues at positions equivalent to +76 and +104, there is also a substitution of an amino acid residue at one or more amino acid residue positions equivalent to positions +99, +101, +103, +107, +123, +27, +105, +109, +126, +128, +135, +156, +166, +195, +197, +204, +206, +210, +216, +217, +218, +222, +260, +265, and/or +274; and(b) one or more cleaning composition materials compatible with the protease enzyme.
