HIV-1 protease is the most effective target for drugs to treat AIDS, however, the long-term therapeutic efficiency is restricted by the rapid development of drug resistant variants. To better understand the molecular basis of drug resistance, crystallographic and kinetic studies were applied to wild-type HIV-1 protease (PR) and drug-resistant mutants, PRV82A, and PRI84V, in complex with substrate analogues, the current drug saquinavir and the new inhibitor UIC-94017 (TMC-114). UIC-94017 was also studied with mutants PRD30N and PRI50V. The drug-resistant mutations V82A, I84V, D30N and I50V participate in substrate binding. Eighteen crystal structures were refined at resolutions of 0.97-1.60A. The high …
