ABSTRACT:
The present invention concerns a method for selecting New PRor PLoperator sequences from lambdoid phages which have different thermostability compared to the wild-type sequence with regard to binding a repressor. In addition new mutated PRor PLoperator sequences and their use for the temperature-regulated expression of genes and for production of improved vaccines is disclosed.
