| abstract |
Combinatorial libraries of different-sequence peptide members is disclosed. The libraries are comprised of stabilized, alpha-helical polypeptides having a similar tertiary structure but different amino acid residues at specific, "variable" positions in the sequence. The polypeptides are stabilized through coiled-coil interactions with other alpha -helical polypeptides and/or via intrahelical lactam bridges. Also disclosed are methods for using such libraries to screen for selected macromolecular ligands. |
