- PublicationRestrictedIntraresidual correlated motions in peptide chains(American Chemical Society, 2019-10-31) Bastida, Adolfo; Carmona García, Javier; Zúñiga, José; Requena, Alberto; Cerezo, Javier; Química FísicaWe investigate the interresidual and intraresidual correlations between dihedral displacements of adjacent residues within model polyalanine peptides by analyzing extensive molecular dynamics trajectories. Correlations are evaluated individually at different residue conformations covering the whole (ϕi ,ψi )-space. From these, we draw maps that unveil an unprecedented strong intramolecular correlation displaying opposite (correlated/anticorrelated) behaviors at different conformations. Both interresidual and intraresidual correlations arise from the propensity of the peptide to minimize the overall atomic displacements.
