| NAB TO GENERATE A FAMILY OF CONFOMRERS THAT SAMPLE A WIDE RANGE OF CONFORMATIONAL SPACE. RESTRAINED MOLECULAR DYNAMICS TO GENERATE A RANGE OF STARTING STRUCTURES FOR DSI. PAIRS OF DNA AND DSI STRUCTURES WERE THEN DOCKED AND ITERATIVELY REFINED BY A SERIES OF RESTRAINED MOLECULAR DYNAMICS CALCULATIONS. | REFINEMENT DETAILS CAN BE FOUND IN THE JRNL CITATION ABOVE. | Amber |
