 AB    We report comprehensive NMR studies in solution of the
       human-immunodeficiency-virus (HIV)-1 protease. Stable solutions of the
       protease were obtained by complexing the protein to a designed cyclic
       urea inhibitor DMP 323. A variety of triple-resonance experiments
       provided essentially complete 1H, 13C and 15N NMR signal assignments of
       the protease. These assignments, together with short-range NOE
       constraints, coupling constants and hydrogen-exchange data, yielded the
       secondary structure of the protease in solution. The results reported
       herein open the way to the determination of the high-resolution
       three-dimensional solution structures of protease/inhibitor complexes,
       as well as to studies of protease dynamics and solvent interactions.
