HIV-1 protease or PR is a retroviral aspartyl protease (retropepsin), an enzyme involved with peptide bond hydrolysis in retroviruses, that is essential for the life-cycle of HIV, the retrovirus that causes AIDS.[1][2] HIV-1 PR cleaves newly synthesized polyproteins (namely, Gag and Gag-Pol[3]) at nine cleavage sites to create the mature protein components of an HIV virion, the infectious form of a virus outside of the host cell.[4] Without effective HIV-1 PR, HIV virions remain uninfectious.[5][6]
