| torsion angle dynamics + restrained energy minimization + restrained molecular dynamics | The structure was calculated using dipolar (NOESY) derived constraints supplemented with phi and psi dihedral angle constraints as well as with hydrogen bond constraints. The mean structure of the DYANA family was initially subjected to restrained energy minimization in vacuo and subsequently to restrained molecular dynamics in explicit water medium.
