Cis-Allosteric Regulation of HIV-1 Reverse Transcriptase by Integrase

open access: yesViruses, 2022
Reverse transcriptase (RT) and integrase (IN) are encoded tandemly in the pol genes of retroviruses. We reported recently that HIV-1 RT and IN need to be supplied as the pol precursor intermediates, in which RT and IN are in fusion form (RTIN) to exert ...
