Correlation of protein structure and dynamics to scalar couplings across hydrogen bonds.

Abstract

NMR-observable scalar couplings across hydrogen bonds in nucleic acids and proteins present a quantitative measure for the geometry and--by the implicit experimental time averaging--dynamics of hydrogen bonds. We have carried out in-depth molecular dynamics (MD) simulations with various force fields on three proteins: ubiquitin, the GB1 domain of protein G… (More)
