Description

3ggu is a drug resistant HIV protease. Shown is a patient's variant in complex with darunavir.

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.

HIV proteases contain a highly conserved region Asp - Thr - Gly (Asp25, Thr26 and Gly27), with the aspartic residue beeing the active site in the aspartyl protease.(1)

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. (2)

3ggu (also PRdrv5) 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. [1]
