Novel protease variants derived from the DNA sequences of naturally-occurring or recombinant non-human proteases are disclosed. The variant proteases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant protease to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor protease. Such variant proteases have properties which are different from those of the precursor protease, such as altered wash performance. The substituted amino acid residue corresponds to position 103 in combination with one or more of the following substitutions at residue positions corresponding to positions 1, 3, 4, 8, 10, 12, 13, 15, 16, 17, 18, 19, 20, 21, 22, 24, 27, 33, 37, 38, 42, 43, 48, 55, 57, 58, 61, 62, 68, 72, 75, 76, 77, 78, 79, 86, 87, 89, 97, 98, 99, 101, 102, 104, 106, 107, 109, 111, 114, 116, 117, 119, 121, 123, 126, 128, 130, 131, 133, 134, 137, 140, 141, 142, 146, 147, 158, 159, 160, 166, 167, 170, 173, 174, 177, 181, 182, 183, 184, 185, 188, 192, 194, 198, 203, 204, 205, 206, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 222, 224, 227, 228, 230, 232, 236, 237, 238, 240, 242, 243, 244, 245, 246, 247, 248, 249, 251, 252, 253, 254, 255, 256, 257, 258, 259, 260, 261, 262, 263, 265, 268, 269, 270, 271, 272, 274, and 275 of Bacillus amyloliquefaciens subtilisin, wherein when a substitution at a position corresponding to residue position 103 is combined with a substitution at a position corresponding to residue position 76, there is also a substitution at one or more residue positions other than residue positions corresponding to positions 27, 99, 101, 104, 107, 109, 123, 128, 166, 204, 206, 210, 216, 217, 218, 222, 260, 265 or 274 of Bacillus amyloliquefaciens subtilisin.

L'invention concerne de nouvelles variantes de protéases obtenues à partir de séquences d'ADN de protéases naturelles ou de protéases non humaines recombinées. Les protéases variantes, en général, sont obtenues par modification in vitro d'une séquence d'ADN précurseur codant pour la protéase naturelle ou recombinée en vue de produire la substitution de plusieurs résidus d'acides aminés dans la séquence d'acides aminés d'une protéase précurseur. Ces protéases variantes possèdent des propriétés différentes de celles de la protéase précurseur, telles que des performances modifiées de lavage. Le résidu d'acides aminés substitués correspond à la position 103, et est combiné avec une ou plusieurs des substitutions suivantes à des positions de résidus d'acides aminés correspondant aux positions 1, 3, 4, 8, 10, 12, 13, 15, 16, 17, 18, 19, 20, 21, 22, 24, 27, 33, 37, 38, 42, 43, 48, 55, 57, 58, 61, 62, 68, 72, 75, 76, 77, 78, 79, 86, 87, 89, 97, 98, 99, 101, 102, 104, 106, 107, 109, 111, 114, 116, 117, 119, 121, 123, 126, 128, 130, 131, 133, 134, 137, 140, 141, 142, 146, 147, 158, 159, 160, 166, 167, 170, 173, 174, 177, 181, 182, 183, 184, 185, 188, 192, 194, 198, 203, 204, 205, 206, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 222, 224, 227, 228, 230, 232, 236, 237, 238, 240, 242, 243, 244, 245, 246, 247, 248, 249, 251, 252, 253, 254, 255, 256, 257, 258, 259, 260, 261, 262, 263, 265, 268, 269, 270, 271, 272, 274, et 275 de Bacillus amyloliquefaciens subtilisine; lorsqu'on combine une substitution à une position correspondant à la position de résidu 103 avec une substitution à une position correspondant à la position de résidu 76, il y a également substitution à une ou plusieurs positions de résidus autres que les positions de résidus correspondant aux positions 27, 99, 101, 104, 107, 109, 123, 128, 166, 204, 206, 210, 216, 217, 218, 222, 260, 265 ou 274 de Bacillus amyloliquefaciens subtilisine.
