Binding of F18 to HIV-1 RT in conformational space. Using computer software, structural binding of F18 or NVP to the HIV-1 RT binding pocket was determined for wild-type (A), the L100I mutant (B), and the Y181C mutant (C). (D) Interaction between the T139 residue and F18. Amino acid residues important for binding interactions are labeled. Indicated elements: carbon (gray), oxygen (red), nitrogen (purple), sulfur (yellow), F18 chloro group (green).
