Figure 1.
Models of 3SCC used in this study. (a) N → C terminus view of TRIL16C showing the three Cys residues at the metal site. (b) TRIL16C oriented perpendicular to the helical axis. Cys16 and the closest Leu layers are shown explicitly. (c) TRIL16CL23A with indication of the Leu23Ala substitution (purple). Protein backbone is shown as green cartoon, thiol groups of Cys as yellow spheres, and Leu layers as white spheres. The model was generated using a 3SCC (Coil Ser) PDB ID 3H5G30 and PyMol.33
