Abstract：
:The structure determination of macromolecular complexes is entering a new era. The methods of optical microscopy, electron microscopy, X-ray crystallography, and nuclear magnetic resonance increasingly are being combined in hybrid method approaches to achieve an integrated view of macromolecular complexes that span from cellular context to atomic detail. A particularly important application of these hybrid method approaches is the structural analysis of the Human Immunodeficiency Virus (HIV) proteins with their cellular binding partners. High resolution structure determination of essential HIV - host cell protein complexes and correlative analysis of these complexes in the live cell can serve as critical guides in the design of a broad, new class of therapeutics that function by disrupting such complexes. Here, with the hope of stimulating some discussion, we will briefly review some of the literature in the context of what could be done to further apply structural methods to HIV research. We have chosen to focus our attention on certain aspects of the HIV replication cycle where we think that structural information would contribute substantially to the development of new therapeutic and vaccine targets for HIV.
