Patent number: 5352603Abstract: 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 The result is highly alkaline proteases in which original amino acids have been replaced by more strongly basic amino acids, preferably by the amino acids lysine or arginine.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.Type: GrantFiled: February 28, 1991Date of Patent: October 4, 1994Assignees: Kali-Chemie AG, Gesellschaft fuer Biotechnologische Forschung mbHInventors: Roman Vetter, Detlef Wilke, Antoine Amory, Andre Clippe, Dietmar Schomburg, Wolfgang Aehle
