Estimating the term…
This invention provides an isolated polypeptide comprising an amino acid sequence of a N-terminal choline binding protein A truncate in which the amino acid sequence is set forth in any of SEQ ID NOS: 1, 3-7, or 9-11, including fragments, mutants, variants, analogs, or derivatives, thereof. Also, this invention provides a isolated polypeptide comprising an amino acid sequence of a N-terminal choline binding protein A truncate, wherein the amino acid is set forth in SEQ ID NO: 24, wherein the polypeptide retains its native tertiary structure and methods of preparation. This invention provides an isolated polypeptide comprising an amino acid sequence of a N-terminal choline binding protein A truncate, wherein the polypeptide has lectin activity and does not bind to choline. This invention provides an isolated immunogenic polypeptide comprising an amino acid sequence of a N-terminal choline binding protein A truncate. This invention provides an isolated nucleic acid encoding a polypeptide comprising an amino acid sequence of a N-terminal choline binding protein A truncate. Lastly, this invention provides pharmaceutical compositions, vaccines, and diagnostic and therapeutic methods of use.
A vaccine for treating or protecting against pneumococcal infection comprising a polypeptide in a pharmaceutically acceptable carrier wherein said polypeptide comprises SEQ ID NO:4, said polypeptide does not bind to choline, said polypeptide exhibits a tertiary structure as found in a native, full-length CbpA polypeptide, and the polypeptide content of said vaccine being in an amount effective for treating or protecting against R6x pneumococcal infection or Type 4 pneumococcal infection.
