Inhibition of foamy virus reverse transcriptase by human immunodeficiency virus type 1 RNase H inhibitors.

ABSTRACT: RNase H plays an essential role in the replication of human immunodeficiency virus type 1 (HIV-1). Therefore, it is a promising target for drug development. However, the identification of HIV-1 RNase H inhibitors (RHIs) has been hampered by the open morphology of its active site, the limited number of available RNase H crystal structures in complex with inhibitors, and the fact that, due to the high concentrations of Mg(2+) needed for protein stability, HIV-1 RNase H is not suitable for nuclear magnetic resonance (NMR) inhibitor studies. We recently showed that the RNase H domains of HIV-1 and prototype foamy virus (PFV) reverse transcriptases (RTs) exhibit a high degree of structural similarity. Thus, we examined whether PFV RNase H can serve as an HIV-1 RNase H model for inhibitor intera
