  • PubMed Abstract: 

    The HIV protease is essential for the life cycle of the virus and is an important target for the development of therapeutic treatments against AIDS. The structures of HIV protease in complex with different inhibitors have helped in understanding the interactions between inhibitors and the protease and in the design and optimization of HIV protease inhibitors.
