    Vibrational spectra of a 12-residue beta hairpin peptide, RYVEVBGKKILQ (HBG), stabilized by an Aib-Gly turn sequence (B=Aib) were investigated theoretically using a combination of molecular dynamics (MD) and density functional theory (DFT) calculations.

    Vibrační spektra modelového 12-peptidu v konformaci beta-hairpin, který je stabilizován sekvencí Aib-Gly, byla teoreticky analyzována za pomoci molekulově mechanických a kvantových DFT výpočtů.
