*Saquinavir (SQV) critical substitutions: red color SQV additional substitutions: green color **Indinavir (IDV) critical substitutions: pink color IDV additional substitutions: yellow color _ Important residues for drug binding and stability: Asp25, Gly 27, Asp29, Asp30, Gly48, Ile50
Table 6: Residue mutations observed in the 15 patients colored according to their known effect on Saquinavir* and Indinavir** resistance. The analysis is focused on the catalytic residues important residues for drug binding and stability (Asp25, Gly 27, Asp29, Asp30, Gly48, Ile50), the residues of the active site (Asp25-Thr26-Gly27), and the residues provoking specific substitutions (see Table, Supplemental Digital Content 3, which shows the HIV-1 mutations that confer resistance to the main protease inhibitors).
