  • Patent number: 6465235
    Abstract: Novel carbonyl hydrolase mutants derived from the amino acid sequence of naturally-occurring or recombinant non-human carbonyl hydrolases and DNA sequences encoding the same. The mutant carbonyl hydrolases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant carbonyl hydrolase to encode the substitution, insertion or deletion of one or more amino acids in the amino acid sequence of a precursor carbonyl hydrolase. Such mutants have one or more properties which are different than the same property of the precursor hydrolase.
    Type: Grant
    Filed: December 18, 1997
    Date of Patent: October 15, 2002
    Assignee: Genenco International, Inc.
    Inventors: Richard Ray Bott, Robert Mark Caldwell, Brian C. Cunningham, David Aaron Estell, Scott Douglas Power, James Allen Wells

  • Patent number: 5939315
    Abstract: Processes for producing various heterologous polypeptides which when expressed are either incorrectly processed and hence asssociated with the surface of the host cell or are not processed to mature form. More specifically, processes for the production of heterologous non-human carbonyl hydrolases expressed either in host cells incapable of producing enzymatically active endoprotease or host cells deficient in enzymatically active extracellular endoprotease are disclosed. Such non-human carbonyl hydrolases generally are incapable of autoproteolytic maturation and become associated with the surface of expression hosts which are deficient in enzymatically active extracellular endoprotease. Processes for preparing non-human carbonyl hydrolase and heterologous polypeptides which are expressed as part of a fusion polypeptide are also disclosed, as well as non-human carbonyl hydrolases which are substantially free of the host cell membrane with which they are normally associated.
