  • Patent number: 9566335
    Abstract: The invention describes methods and reagents useful for sequencing polypeptide molecules. The method comprises affixing a polypeptide to a substrate and contacting the polypeptide with a plurality of probes. Each probe selectively binds to an N-terminal amino acid or an N-terminal amino acid derivative. Probes bound to the polypeptide molecule are then identified before cleaving the N-terminal amino acid or N-terminal amino acid derivative of the polypeptide. Also provided are methods for the sequencing a plurality of polypeptide molecules in a sample and probes specific for N-terminal amino acids or N-terminal amino acid derivatives.

  • Publication number: 20160223560
    Abstract: Methods and compositions for identifying D-peptidic compounds that specifically bind target proteins are provided. Aspects of the methods include screening libraries of 20 residue or more L-peptidic compounds for specific binding to 40 residue or more D-target proteins. Once a L-peptidic compound has been identified that specifically binds to the D-target protein, the D-enantiomer of that compound may be produced.

  • Publication number: 20150376604
    Abstract: Scaffolded peptidic libraries and methods of screening the same for specific binding to a target protein are provided. Each library includes distinct peptidic compounds that include a scaffold domain and a distinct variable domain. A variety of libraries are provided where each library is based on an underlying peptidic scaffold having a structural motif. In some embodiments, the peptidic scaffold is a small protein having a protein-protein interaction surface. Libraries of polynucleotides that encode a variety of peptidic compounds are provided. These libraries find use in a variety of applications in which specific binding to target molecules, e.g., target proteins is desired. Also provided are methods of making the libraries and methods of screening the libraries for binding to a target.
