| abstract |
The invention relates to proteases comprising an amino acid sequence which has at least 70% sequence identity with the amino acid sequence given in SEQ ID NO: 1 over its entire length and amino acid substitutions (a) at the positions corresponding to positions 9 and 271, in each case based on the numbering according to SEQ ID NO: 1, and (b) d at at least one of the positions corresponding to the positions 29, 48, 101, 130, 131, 133, 144, 224 or 252, in each case based on the numbering according to SEQ ID NO: 1 , correspond, have and their preparation and use. Such proteases show a very good cleaning performance. |
