    The structure of pseudoazurin from Thiosphaera pantotropha has been determined and compared to structures of both soluble and membrane-bound periplasmic redox proteins. The results show a matching set of unipolar, but promiscuous, docking motifs based on a positive hydrophobic surface patch on the electron shuttle proteins pseudoazurin and cytochrome c550 and a negative hydrophobic patch on the surface of their known redox partners. The observed electrostatic handedness is argued to be associated with the charge-asymmetry of the membrane-bound components of the redox chain due to von Heijne's 'positives-inside' principle. We propose a 'positives-in-between' rule for electron shuttle proteins, and expect a negative hydrophobic patch to be present on both the highest and lowest redox potential species in a series of electron carriers.
