Unlike most members of aspartyl protease class, which generally exist as two domain monomers, HIV protease is a dimmer with two identical subunits that are comprised of 99 amino acids. The HIV PR, together with single stranded RNA (ssRNA), reverse transcriptase, integrase, and other viral factors, is found inside the HIV-1 virion. As an important viral protein, it plays a crucial role in successful viral propagation.
