HIV-1 reverse transcriptase (RT) is an important drug target. RT has two activities, DNA synthesis, and cleavage of a DNA–RNA hybrid. These activities require that RT bind to both DNA and RNA. Single-molecule technology is used to show that the enzyme binds to RNA and DNA in different orientations, and provide insight into how it can flip between these orientations and activities without dissociating from the substrate.
