Proteases may include an amino acid sequence having at least 70% sequence identity with the amino acid sequence given in SEQ ID NO: 1 over its entire length and, in each case based on the numbering according to SEQ ID NO: 1, may include (i) amino acid substitutions, such as selected from amino acid substitutions 9T, 144K, 252T and 271E, at positions corresponding to positions 9, 144, 252 and 271, and (ii) at least one additional amino acid substitution at least at one of the positions corresponding to positions 53, 120, 131, 149, 159, 162, 166, 172, 189, 192, 211, 215, 217, 224 and 274. Production and use of said proteases are described herein. Proteases of this kind demonstrate very good stability with a good cleaning performance.
