Abstract

Official abstract text for this publication.

Proteases that comprise an amino acid sequence that is at least 70% identical to the amino acid sequence indicated in SEQ ID NO. 1 over its entire length and that comprise, in the count in accordance with SEQ ID NO. 1, the amino acid substitution R99D in combination with at least two further amino acid substitutions that are selected from the group consisting of S3T, V4I, and V199I, display very good cleaning performance in particular on blood-containing stains, as well as very good temperature stability.

First claim

Opening claim text (preview).

What is claimed is: 1. A washing or cleaning agent comprising a polypeptide that is at least 98% identical to the amino acid sequence indicated in SEQ ID NO. 1, wherein the polypeptide has protease activity, and comprises in position 99 in the numbering according to SEQ ID NO. 1 the amino acid glutamic acid (E) or aspartic acid (D) and S3T, V4I, and V199I, and comprises, by weight, 0.3 to 0.5% xanthan, 4 to 7% fatty alcohol ether sulfate, 24 to 28% nonionic surfactants and 0.5% 1-hydroxyethane-(1,1-diphosphonic acid). 2. A method for manufacturing the protease of claim 1 , comprising introduction of the amino acid substitution R99E or R99D in combination with the amino acid substitutions S3T, V4I, and V199I in the count according to SEQ ID NO. 1.
