Abstract: Single molecule fluorescence resonance energy transfer (SMFRET) has been used to characterize the nucleocapsid protein- chaperoned minus-strand transfer step that occurs during HIV-1 reverse transcription. The technique has allowed us to classify bond formation and nucleic acid structure involved in HIV-1 reverse transcription with unprecedented resolution. The single molecule results reveal two competing annealing pathways, a conclusion obscured by alternate ensemble techniques. We also have measured protein-induced nucleic acid structural dynamics associated with chaperoning the preferred annealing pathway. Finally, the resolving power of SMFRET has been used to characterize a model reverse transcription inhibitor, which was found to be successful against only one of the two annealing pathways. Such molecular-level detail in drug efficacy analysis could help us to rectify the inefficiency of current therapeutic options caused by rapid viral mutation and multiple reaction pathways.
