Interaction of fluorescently labeled dideoxynucleotides with HIV-1 reverse transcriptase.

Abstract

Succinylfluorescein-labeled dideoxyTTP has been used as a substrate for reverse transcriptase from HIV-1. On addition to the 3'-end of a primer molecule, there is a reduction of fluorescence yield of a factor of ca. 4. Release of a fluorescent DNA/DNA primer/template duplex from its complex with reverse transcriptase results in a reduction of fluorescence… (More)
