Abstract:
This article describes a strategy to develop, starting from a de novo design, bivalent peptides containing two different (alpha-helix and beta-hairpin) and independent secondary-structure elements. The design was based on the use of conformationally restricted peptide libraries. Structural characterization by NMR revealed that the peptides were stable and did not show any long-range NOE interactions between the N-terminal beta-hairpin and the C-terminal alpha-helix. These results suggest that the two elements of secondary structure are stable and well folded.
