  • Title: On the similarity of properties in solution or in the crystalline state: a molecular dynamics study of hen lysozyme.
    Author: Stocker U, Spiegel K, van Gunsteren WF.
    Journal: J Biomol NMR; 2000 Sep; 18(1):1-12. PubMed ID: 11061223.
    Abstract:
    As protein crystals generally possess a high water content, it is assumed that the behaviour of a protein in solution and in crystal environment is very similar. This assumption can be investigated by molecular dynamics (MD) simulation of proteins in the different environments. Two 2ns simulations of hen egg white lysozyme (HEWL) in crystal and solution environment are compared to one another and to experimental data derived from both X-ray and NMR experiments, such as crystallographic B-factors, NOE atom-atom distance bounds, 3J(H N alpha)-coupling constants, and 1H-15N bond vector order parameters. Both MD simulations give very similar results. The crystal simulation reproduces X-ray and NMR data slightly better than the solution simulation.
