Abstract
Polyamines, especially branched polyamines such as tetrakis(3-aminopropyl)ammonium (Taa), stabilize the tertiary structure of RNA molecules. In this study, we examined the polyamine binding site of the HIV-1 dimerization initiation site (DIS) in the kissing-loop dimer by the docking simulation. It was found that Taa binds predominantly to the kissing loop interaction site of DIS.
