The aim of the invention is for a phosphonate-containing liquid detergent or cleaning agent to exhibit an advantageous proteolytic activity and additionally to have improved storage stability. Said aim is achieved by using a protease which comprises an amino acid sequence that is at least 80% identical to the amino acid sequence set forth in SEQ ID NO. 1 and contains, at position 99 of SEQ ID NO. 1, the amino acid glutamic acid (E) or aspartic acid (D), or the amino acid asparagine (N) or glutamine (Q), or the amino acid alanine (A) or glycine (G) or serine (S). |
