Publication number: 20220154110
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 has, in each case based on the numbering according to SEQ ID NO:1, (i) amino acid substitutions, preferably selected from the amino acid substitutions 9T, 144K, 252T and 271E, at the positions corresponding to positions 9, 144, 252 and 271; and (ii) at least one further amino acid substitution at at least one of the positions corresponding to positions 18, 38, 48, 89, 101, 131, 145, 147, 149, 162, 166, 172, 189, 192, 205, 211, 215, 217, 218, 224 and 274. The invention also relates to the production and use of said proteases. Proteases of this type exhibit a very good cleaning performance.

Publication number: 20210163912
Abstract: An amino acid sequence may have at least 70% sequence identity to the amino acid sequence identified in SEQ ID No. 1 over its entire length, and (a) an amino acid substitution on the position corresponding to the position 271, and (b1) at least one other amino acid substitution for at least one of the positions corresponding to the positions 18, 61, 92, 99, 137, 149, 156, 159, 162, 166, 172, 192, 199, 217, 265, or combinations thereof; and/or (b2) an amino acid substitution on the position corresponding to the position 9, and another amino acid substitution for at least one position corresponding to the positions 29, 48, 101, 130, 31, 133, 144, 217, 224, 252, or combinations thereof. Such proteases are useful for in washing or cleaning agents.

Publication number: 20200172890
Abstract: Proteases may include 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 has (i) one or more first amino acid substitutions at positions corresponding to positions 3, 4, 99, 199, or combinations thereof, and (ii) one or more second amino acid substitutions at positions corresponding to positions 9, 21, 42, 44, 105, 112, 113, 131, 137, 139, 141, 145, 159, 168, 176, 177, 182, 193, 198, 204, 205, 206, 210, 212, 230, 234, 250, 253, 255, 259, 267, or combinations thereof based on the numbering according to SEQ ID NO:1, and relates to the preparation and use thereof. Proteases of this kind demonstrate very good stability with good cleaning performance.
