Ada protein-RNA polymerase sigma subunit interaction and alpha subunit-promoter DNA interaction are necessary at different steps in transcription initiation at the Escherichia coli Ada and aidB promotersP Landini
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...
The Escherichia coli Ada protein can interact with two distinct determinants in the sigma70 subunit of RNA polymerase according to promoter architecture: identification of the target of Ada activation at the alkA promoterP Landini
School of Biochemistry, The University of Birmingham, Edgbaston, Birmingham B15 2TT, United Kingdom
J Bacteriol 181:1524-9. 1999..We propose that meAda can activate transcription at different promoters by contacting distinct determinants in sigma70 region 4 in a manner dependent on the location of the Ada binding site...
Activation and repression of transcription initiation in bacteriaG 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...
The leucine-responsive regulatory protein (Lrp) acts as a specific repressor for sigma s-dependent transcription of the Escherichia coli aidB geneP 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...
The RNA polymerase alpha subunit carboxyl-terminal domain is required for both basal and activated transcription from the alkA promoterP Landini
Department of Molecular Genetics and Microbiology, University of Massachusetts Medical School, Worcester, Massachusetts 01655, USA
J Biol Chem 272:15914-9. 1997..These observations suggest that both forms of Ada protein activate alkA transcription by enhancing RNA polymerase holoenzyme and alpha subunit binding...
Structure and transcriptional regulation of the Escherichia coli adaptive response gene aidBP Landini
Department of Molecular Genetics and Microbiology, University of Massachusetts Medical School, Worcester 01655
J Bacteriol 176:6583-9. 1994..Ada protein plays a direct role in aidB regulation: methylated Ada is able to bind to the aidB promoter region and to activate transcription from aidB in an in vitro transcription-translation system using crude E. coli extracts...
Transcriptional activation of the Escherichia coli adaptive response gene aidB is mediated by binding of methylated Ada protein. Evidence for a new consensus sequence for Ada-binding sitesP Landini
Department of Molecular Genetics and Microbiology, University of Massachusetts Medical School, Worcester 01655, USA
J Biol Chem 270:8285-9. 1995..We propose that these elements, in addition to the proposed recognition sequence, are important for binding of the Ada protein...
Expression of the Escherichia coli ada regulon in stationary phase: evidence for rpoS-dependent negative regulation of alkA transcriptionP Landini
Swiss Federal Institute for Environmental Science and Technology EAWAG, 8600 Dubendorf, Switzerland
J Bacteriol 181:6836-9. 1999..Thus, at the alkA promoter, the Ada protein can act as both a positive and negative modulator of the adaptive response to alkylation damage, depending on the cell's physiological state...
Regulatory responses of the adaptive response to alkylation damage: a simple regulon with complex regulatory featuresP Landini
Department of Environmental Microbiology and Molecular Ecotoxicology, Swiss Institute for Environmental Technology, 8600 Duebendorf, Switzerland
J Bacteriol 182:6543-9. 2000
Transcriptional responses to DNA damageM R Volkert
Department of Molecular Genetics and Microbiology, University of Massachusetts Medical School, Worcester, MA 01605, USA
Curr Opin Microbiol 4:178-85. 2001..Transcription of the responses to DNA damage are induced when the activated regulatory proteins stimulate transcription of the genes they control by a variety of complex and unique molecular mechanisms...
Complex regulatory network controls initial adhesion and biofilm formation in Escherichia coli via regulation of the csgD geneC Prigent-Combaret
Unité de Microbiologie et Génétique, CNRS UMR 5122, Institut National des Sciences Appliquees de Lyon, 69621 Villeurbanne Cedex, France
J Bacteriol 183:7213-23. 2001....
RNA polymerase alpha subunit binding site in positively controlled promoters: a new model for RNA polymerase-promoter interaction and transcriptional activation in the Escherichia coli ada and aidB genesP Landini
Department of Molecular Genetics and Microbiology, University of Massachusetts Medical School, Worcester 01655, USA
EMBO J 14:4329-35. 1995..Instead, Ada stimulates transcription by modifying the nature of the RNA polymerase-promoter interaction, allowing RNA polymerase to recognize the core promoter -35 and -10 elements in addition to the UP-like element...
