  • 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.
