WebStabilized α-helices and nonpeptidic helix mimetics have emerged as powerful molecular scaffolds for the discovery of protein-protein interaction inhibitors. Protein-protein interactions often involve large contact areas, which are often difficult for small molecules to target with high specificity. WebAlpha helix is a secondary structure of proteins or polymers of peptides that have a rigid, rod like structure. These polypeptide chains can be both left and right-handed but the right-handed ones are more commonly found secondary structure of protein. Side chains of the polypeptides are faced out and away from the helix.

Web14 nov. 2000 · The effect of TFE on the stability of the α-helix formed by the ribonuclease S-peptide (residues 1–19 of ribonuclease A) was studied by Nelson and Kallenbach using circular dichroism techniques. According to these authors, the most striking observation from their experiments is that the helix-stabilizing interactions afforded by the charged groups … Web2 aug. 2012 · Horovitz A, Matthews JM, Fersht AR: Alpha-helix stability in proteins.

WebAlpha helices are largely stabilized by backbone hydrogen bonding. That is, local interactions dominate in a helix, whereas a sheet is stabilized by long range contacts. WebThe structure shows that the hydrogen-bond surrogate (HBS) derived α-helix truly resembles the structure of canonical α-helices and provides unequivocal support for our helix nucleation strategy.
