Figure 6From: Natural polymorphisms and unusual mutations in HIV-1 protease with potential antiretroviral resistance: a bioinformatic analysisHIV-1 protease structures. Wild-type (WT), resistant and D29V mutant proteases coupled to darunavir (top) and tipranavir (bottom). The numbers in the left upper corner are the PDB ID numbers used to model darunavir and tipranavir with the protease and to measure the distance (Ã…) between functional groups (purple).Back to article page
