Figure 3 Stereo diagrams of the protein surfaces of rapamycin complexes of FKBP12.6 and FKBP12. The rapamycin is shown in ball-and-stick format, colored white, red and blue for carbon, oxygen and nitrogen, respectively. The protein surfaces are colored by chemical property: white is hydrophobic, red is negatively charged, blue is positively charged, orange is a hydrogen-bond acceptor, cyan is a hydrogen-bond donor and magenta can both accept and donate hydrogen bonds. Exposed surfaces of non-identical residues are textured with a mesh and labeled. The orientation is as in Fig. 1-(b), only 90% smaller. Above, FKBP12.6; below, FKBP12.
