Importance of the conserved lysine 83 residue of Zea mays cytochrome b(561) for ascorbate-specific transmembrane electron transfer as revealed by site-directed mutagenesis studies.

8 Nov 2009 Cytochromes b(561), a novel class of transmembrane electron transport proteins residing in a large variety of eukaryotic cells, have a number of common structural features including six hydrophobic transmembrane alpha-helices and two heme ligation ... Read more...

Monitoring the iron status of the ferroxidase center of Escherichia coli bacterioferritin using fluorescence spectroscopy.

27 Sep 2009 Ferritins solubilize and detoxify the essential metal iron through formation of a ferric mineral within the protein's central cavity. Key to this activity is an intrasubunit catalytic dinuclear iron center called the ferroxidase center. Here we show ... Read more...

Respiration of Escherichia coli can be fully uncoupled via the nonelectrogenic terminal cytochrome bd-II oxidase.

17 Jun 2009 The respiratory chain of Escherichia coli is usually considered a device to conserve energy via the generation of a proton motive force, which subsequently may drive ATP synthesis by the ATP synthetase. It is known that in this system a fixed amount ... Read more...
