First the structure of the dimeric lac HP62-V52C was calculated using only protein NMR restraints. The 50 best structures were selected and docked onto the natural lac operator B-DNA using simulated annealing. Distance and planarity restraints for the DNA were incorporated in order to keep DNA close to B-DNA but allowing a bend necessary to accommodate the two headpiece molecules on the DNA. | ||||||||||||||||||||||||
