Temporal Coordination between Initiation of HIV (+)-Strand DNA Synthesis and Primer Removal

Abstract excerpt

In this study, we have analyzed the interdependence between the polymerase and RNase H active sites of human immunodeficiency virus-1 reverse transcriptase (RT) using an in vitro system that closely mimics the initiation of (+)-strand DNA synthesis. Time course experiments show that RT pauses after addition of the 12th DNA residue, and at this stage the RNase H activity starts to cleave the RNA primer from newly...
