✦ Synopsis
The experimental carbon- 13 relaxation times of BPTI have been compared with the values predicted by molecular-dynamics simulations. Since the carbon-13 (T_{1}) values are sensitive monitors of the rates and amplitudes of the internal motions of the protein, this comparison was made to test the extent to which molecular dynamics provides an accurate depiction of the internal motions of proteins. The experimental and predicted amide-alpha scalar couplings were also compared, since this coupling is dependent on the conformation of the protein. These comparisons have shown that the molecular-dynamics simulation predicts results that are in good overall agreement with the experimental data. (1) 1994 Academic Press, Inc.
