Torsion angle molecular dynamics. Refinement and energy minimization in a water shell using Cartesian dynamics and powell minimization. | Initial structures were generated by torsion angle dynamics. These were then refined and minimized in a water shell using Cartesian dynamics and restrained powell minimization according to ARIA and CNS protocols. | XwinNMR |
