HIV-1 protease (PR) has been extensively studied due to its importance as a target in AIDS therapy. The enzyme can be obtained via expression of its cloned gene in an appropriate system, or via chemical synthesis. We required a reliable source of fluorine-labeled HIV-1 protease for NMR studies. As our attempts to incorporate a labeling step in overexpression experiments in E. coli failed, we turned to chemical synthesis. Herein is described the first chemical synthesis of an active, 99 amino acid residue HIV-1 encoded protease using Fmoc-chemistry on a total PEG-based resin (CM resin), and labeled with 19F at the Phe residue. Also reported here are NMR studies of the labeled synthetic protein with a synthetic dimerization inhibitor.
