  • Patent number: 7332320
    Abstract: The present invention provides novel protein variants that exhibit reduced immunogenic responses, as compared to the parental proteins. The present invention further provides DNA molecules that encode novel variants, host cells comprising DNA encoding novel variants, as well as methods for making proteins less allergenic. In addition, the present invention provides various compositions that comprise these proteins that are less immunogenic than the wild-type proteins.

  • Patent number: 7329498
    Abstract: The present invention provides means to identify functional CD8+ T-cell epitopes in any protein of interest. The present invention further provides CD8+ T-cell epitopes of various proteins. In additional embodiments, the present invention provides epitopes suitable for use in prophylactic and/or therapeutic vaccines. In particularly preferred embodiments, the present invention provides modified epitopes suitable for use in prophylactic and/or therapeutic vaccines. In some preferred embodiments, the present invention provides means for the development of HPV vaccines, in particular multivalent vaccines for the prevention of infection with high-risk HPV strains. In particular, the present invention provides means to identify CD8+ T-cell epitopes in HPV strains such as HPV 16 and HPV 18. In additional embodiments, the present invention provides means for the development of therapeutic vaccines against high-risk HPV types that prevent the development of benign and/or malignant tumors in infected individuals.

  • Patent number: 7329528
    Abstract: An enzyme multimer is provided which comprises a plurality of monomer units including a first monomer unit having enzymatic activity and a second monomer unit having enzymatic activity, wherein each of the first monomer unit and the second monomer unit comprise a cysteine residue and the cysteine residues of each monomer unit are covalently bound to each other through a disulfide bond to covalently attach the first monomer unit to the second monomer unit.

  • Patent number: 7306937
    Abstract: Novel enzyme variants including protease variants derived from the DNA sequences of naturally-occurring or re-combinant non-human proteases are disclosed. The variant proteases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant protease to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor protease. Such variant proteases have properties which are different from those of the precursor protease, such as altered wash performance. The substituted amino acid residue correspond to positions 27, 45, 170, 181, 251 and 271 of Bacillus amyloliquefaciens subtilisin. Additional variants comprising at least one additional substitution at a position selected from 1, 14, 49, 61, 87, 100, 102, 118, 128, 204 and 258 of Bacillus amyloliquefaciens subtilisin are also described.

  • Patent number: 6677139
    Abstract: The present invention provides methods for the production of proteins, particularly toxic proteins, in host cells. The invention provides methods which use a fusion protein comprising a chaperonin binding domain in host cells induced or regulated to have increased levels of chaperonin which binds the chaperonin binding domain.
