Figure 1

PyMol model of α3DIV generated from the NMR structure of α3D. Cys residues, located at the C-terminal end of the bundle are shown as spheres. The protein backbone is shown in orange. The Cys site can be considered to be located in a hydrophobic “box” formed by the hydrophobic residues F31, I14, I63, L21, and Y70, shown as sticks.
