Figure 5From: Natural polymorphisms and unusual mutations in HIV-1 protease with potential antiretroviral resistance: a bioinformatic analysisWild-type and D29V mutant protease structures. The structure of the wild-type HIV-1 protease (WT) was obtained by X-ray crystallography. [PDB: 1GNO] (blue), and the mutant protease (green) can be clearly seen, with the red structures corresponding to the oxygen atoms of D29.Back to article page
