The structure of the "bound" conformation of the HIV-1 capsid protein (in the
presence of the ligand) was obtained from the crystal. The complex was
calculated using NMR distance restraints in reference to the bound
conformation of the capsid protein. Refinement was performed using simulated
molecular dynamics in AMBER 9.0.
