An example of interface containing a hub protein. The interface between a transducin with a cGMP phosophodiesterase ([PDB:1FQJ], resolution: 2.02 Å, wetness: 0.032, rWBL: 0.869). Only the transducin (in surfaces) and interfacial water molecules (in spheres) are shown. O0, O1, O2, O3 and non-interface are colored red, brown, yellow, blue and green, respectively.
