  • Patent number: 5260207
    Abstract: The present invention provides a method for redesigning proteins to increase the stability of the protein by altering amino acid residue(s) that are in close proximity to the protein's metal ion binding site(s). Further, the invention is directed to proteins that have been redesigned to have enhanced stability according to the methods of this invention.

  • Patent number: 5202236
    Abstract: Vectors are provided that are capable of expressing, in microbial transformants, a protein having the native amino acid sequence of a bioadhesive precursor protein of a marine animal selected from the group consisting of mussels, barnacles, and oysters. The bioadhesive precursor protein can be expressed in transformants, recovered and converted to a bioadhesive protein by hydroxylation.

  • Patent number: 5162216
    Abstract: This invention is directed to a novel hybrid regulatory region for directing and regulating transcription and translation of a gene sequence positioned downstream from the hybrid regulatory region. This hybrid regulatory region includes the promoter sequence of the phage lambda P.sub.R promoter-operator region fused to the operator sequence of the phage lambda P.sub.L promoter-operator region.
