  • High-alkaline protease and its use arginine-substituted subtilisin composition and use
    Patent number: 6190904
    Abstract: The invention relates to a novel high-alkaline protease, its use in the industrial or domestic fields and also compositions for said uses containing this protease. The protease of the invention is a selected triple mutant derived from certain precursor proteases from the subtilisin group, especially of the “subtilisin 309” type.

  • Stabilized enzymes and process for preparing them
    Patent number: 5453372
    Abstract: Enzymes stabilized against the destabilizing effect of ionic surfactants and a method of producing such stabilized enzymes in which DNA sequences which code for the enzymes are modified by directed mutation in defined positions which correlate with defined surface regions of the enzyme, in such a way that the codon in which the mutation is located now codes for an amino acid differing from the original amino acid.

  • Highly alkaline proteases
    Patent number: 5352603
    Abstract: Novel, optimized highly alkaline proteases which are suitable for use in detergent formulations are prepared by employing microorganisms transformed by mutated DNA sequences. The mutated sequences are obtained starting from DNA sequences which code for highly alkaline protease usually produced by Bacillus species by altering these DNA sequences in defined positions by directed mutagenesis (point mutation) in such a way that the codon in which the point mutation is located now codes for an amino acid which is more strongly basic than the original amino acid. The result is highly alkaline proteases in which original amino acids have been replaced by more strongly basic amino acids, preferably by the amino acids lysine or arginine. Synthetic oligonucleotides, DNA sequences, vectors and transformed microorganisms which are used for generating and obtaining the optimized highly alkaline protease are also described.
