HIV proteases (PR) are essential for the functioning of the retrovirus that causes AIDS. HIV needs active proteases to process gag & gap - polymerase polyprotein precursors into mature structural proteins and replicative enzymes.

Because of its importance for the life-cycle of the retrovirus, HIV-PR are the major target for anti-HIV treatment.

HIV protease inhibitors are the most potent agens used in anti-HIV treatment. However it occurs that HIV-PR develop a resistance to the inhibitor. <ref> PMID:12543689 </ref>

3ggu (also PR<sub>DRV5</sub>) is a mutated clinically derived PR that shows phenotypical resistance to darunavir. Darunavir is a human immunodeficiency virus (HIV) protease (PR) inhibitor (PI) which has inhibiting effects on many HIV type 1 PR variants that show resistance to earlier-generation-PIs. <ref name="Molecular"> PMID:19535439 </ref>
