HIV-1 protease

HIV-1 protease labelled according to its resemblance to an English Bulldog or a fat cat.[7]  The blue and cyan-green ribbons depict the peptide backbone of a wild-type (1D4S​) and a mutant (1KZK​) structure, respectively.
The HIV-1 protease dimer (green and cyan) with active site Asp-25 in red.Complexed with a polypeptide substrate (magenta). (PDB: 1KJF​)Complexed with inhibitor BEA369 (depicted as a sticks with carbon in white, nitrogen in blue, oxygen in red). (PDB: 1EBY​)

HIV-1 protease is a retroviral aspartyl protease (retropepsin) that is essential for the life-cycle of HIV, the retrovirus that causes AIDS. HIV protease cleaves newly synthesized polyproteins at the appropriate places to create the mature protein components of an infectious HIV virion. Without effective HIV protease, HIV virions remain uninfectious. Thus, mutation of HIV protease's active site or inhibition of its activity disrupts HIV’s ability to replicate and infect additional cells, making HIV protease inhibition the subject of considerable pharmaceutical research.
