NMR Refinement
Method	Details	Software
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
