Introduction - This script shows the structure of the HIV protease. Scroll down until the text corresponding to the view is visible. (based on 1hvs.pdb, E.T.Baldwin ,et al., Nat. Struct. Biol. 2 244 (1995)).
The HIV protease contains two identical subunits (RED and GREEN). The active site is defined by these two Asp.
Here is a complex between the HIV protease and an inhibitor.
In this view we see the location of V82 and I84.
