Abstract

Proteases encompassing an amino acid sequence, which are at least 70% identical to the amino acid sequence specified in SEQ ID NO. 1 over the entire length thereof and which, in the listing according to SEQ ID NO. 1, have the amino acid substitution I21V in combination with at least one further amino acid substitution, the further amino acid substitution being selected from the group consisting of Q12L, M122L, N177V, A222S, V228I and T247N, and agents encompassing such proteases, exhibit very good cleaning performance on egg-containing stains.
