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.
