[Generalized ordering parameter S2 for N-H peptide bonding as measure of the conformational flexibility of proteins:
Abstract:
NMR spectroscopy in combination with molecular dynamics (MD) simulation technique is a powerful tool for investigation of biomolecule conformations. In the present study we compare the two algorithms of calculation of the generalized order parameter S2 for the peptide N-H bond from MD simulation data. The program based on this algorithm has been written and the effect of an adjustible parameter on results of calculation was studied. HIV-1 protease MD simulation was performed during 7.36 ns using GROMACS 3.1.4. software package. The calculated order parameter values are in good agreement with those obtained by other authors using NMR.

Four types of noncovalent interactions are hydrogen bonds, van der Waals forces, ionic bonds, and hydrophobic interactions.

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
