Conformational analysis of Ac-NPGQ-NH(2) and Ac-VPaH-NH(2) by vibrational circular dichroism spectroscopy combined with molecular dynamics and quantum chemical calculations.
Conformational properties of two potentially beta-turn forming peptides were determined using a strategy which combines MD simulations, IR and VCD spectroscopy and quantum chemical calculations. This strategy could be a useful alternative for solution conformational analysis of short flexible peptides and could help to identify VCD features which are as yet unknown.
