| abstract |
The present invention provides variants of serine proteases of the S1 class with altered sensitivity to one or more activity-modulating substances. A method for the generation of such proteases is disclosed, comprising the provision of a protease library encoding polynucleotide sequences, expression of the enzymes, screening of the library in the presence of one or several activity-modulating substances, selection of variants with altered sensitivity to one or several activity-modulating substances and isolation of those polynucleotide sequences that encode for the selected variants. |
