    School of Biochemistry, University of Birmingham, Edgbaston, Birmingham B15 2TT, United Kingdom
    J Biol Chem 273:13307-12. 1998
    ..Based on these observations, we propose that the role of the alpha subunit at ada and aidB is to allow initial binding of RNA polymerase to the promoters. However, transcription initiation is dependent on meAda-sigma70 interaction...

    School of Biochemistry, The University of Birmingham, Edgbaston, Birmingham B15 2TT, United Kingdom
    J Bacteriol 181:1524-9. 1999

    G Lloyd
    School of Biosciences, University of Birmingham, Edgbaston, Birmingham B15 2TT
    Essays Biochem 37:17-31. 2001
    ..Many promoters are regulated by more than one transcription factor. A variety of mechanisms whereby a promoter can be regulated by a repressor and an activator, or by two activators, is known...

    P Landini
    Department of Molecular Genetics and Microbiology, University of Massachusetts Medical School, Worcester 01655, USA
    Mol Microbiol 20:947-55. 1996
    ..Leucine counteracts Lrp binding to P aidB, as does binding to P aidB of me Ada, which causes Lrp to dissociate from the promoter. The physiological significance of aidB transcription regulation is discussed...
