HIV-1 protease is an important target for the development of antiviral inhibitors to treat AIDS. A room-temperature joint X-ray/neutron structure of the protease in complex with clinical drug amprenavir has been determined at 2.0 Å resolution. The structure provides direct determination of hydrogen atom positions in the enzyme active site. Analysis of the enzyme-drug interactions suggests that some hydrogen bonds may be weaker than deduced from the non-hydrogen interatomic distances. This information may be valuable for the design of improved protease inhibitors.
