    R Welter
    Department of Biochemistry and Molecular Biology, Oklahoma State University, Stillwater 74078
    J Biol Chem 269:28834-8. 1994
    ..This suggests that the ubiquinol-binding site of the cytochrome bo3 complex is located at least partially on subunit II...

    S Lindquist
    Department of Microbiology, University of Umea, Sweden
    Mol Microbiol 9:703-15. 1993
    ..In addition, we show that transcription is probably not regulated by either the starvation specific sigma factor RpoS, which controls bolA, or by AmpD the negative regulator for ampC transcription...
  54. ncbi Crystallization and preliminary X-ray analysis of the periplasmic fragment of CyoA-a subunit of the Escherichia coli cytochrome o complex
    J van der Oost
    European Molecular Biology Laboratory, Heidelberg, Germany
    J Mol Biol 229:794-6. 1993
    b>CyoA, an integral membrane protein, is a subunit of the Escherichia coli cytochrome o quinol oxidase complex. The C-terminal periplasmic domain of CyoA has been expressed in E. coli, purified and crystallized...

    Department of Microbiology and Molecular Genetics, University of California, Los Angeles 90095, USA
    J Bacteriol 178:1094-8. 1996
    ..These two transcriptional regulators coordinate the hierarchial control of respiratory pathway gene expression in E. coli to ensure the optimal use of oxygen in the cell environment...
  56. ncbi Identification of heme and copper ligands in subunit I of the cytochrome bo complex in Escherichia coli
    J Minagawa
    Department of Biology, Faculty of Science, University of Tokyo, Japan
    J Biol Chem 267:2096-104. 1992
    ..We present a helical wheel model of the redox center in subunit I, which consists of the membrane-spanning regions II, VI, VII, and X, and discuss the implications of the model...
