J Chem Inf Model. 2016 Sep 26;56(9):1798-807

Authors: Haensele E, Saleh N, Read CM, Banting L, Whitley DC, Clark T


Abstract
Arginine vasopressin (AVP) has been suggested by molecular-dynamics (MD) simulations to exist as a mixture of conformations in solution. The (1)H and (13)C NMR chemical shifts of AVP in solution have been calculated for this conformational ensemble of ring conformations (identified from a 23 ?s molecular-dynamics simulation). The relative free energies of these conformations were calculated using classical metadynamics simulations in explicit water. Chemical shifts for representative conformations were calculated using density-functional theory. Comparison with experiment and analysis of the results suggests that the (1)H chemical shifts are most useful for assigning equilibrium concentrations of the conformations in this case. (13)C chemical shifts distinguish less clearly between conformations, and the distances calculated from the nuclear Overhauser effect do not allow the conformations to be assigned clearly. The (1)H chemical shifts can be reproduced with a standard error of less than 0.24 ppm (
