ABSTRACT The RhaS and RhaR proteins are transcription activators that respond to the availability of l-rhamnose and activate transcription of the operons in the Escherichia colil-rhamnose catabolic regulon. RhaR activates transcription of rhaSR, and RhaS activates transcription of the operon that encodes the l-rhamnose catabolic enzymes, rhaBAD, as well as the operon that encodes the l-rhamnose transport protein, rhaT. RhaS is 30% identical to RhaR at the amino acid level, and both are members… Expand
Cyclic AMP Receptor Protein and RhaR Synergistically Activate Transcription from the l-Rhamnose-Responsive rhaSR Promoter in Escherichia coli
TLDR
It appears that CRP activates transcription from rhaSR as it would at simple class I promoters, albeit from a relatively distant position. Expand
The AraC/XylS Family Activator RhaS Negatively Autoregulates rhaSR Expression by Preventing Cyclic AMP Receptor Protein Activation
TLDR
This work further investigated the previous finding that rhaS deletion resulted in a threefold increase in rhaSR promoter activity and proposed a model in which differential DNA bending by RhaS and RhaR may be the basis for the difference in CRP coactivation. Expand
Transcription Activation by the DNA-Binding Domain of the AraC Family Protein RhaS in the Absence of Its Effector-Binding Domain
TLDR
RhaS-CTD contains all of the determinants necessary for transcription activation by RhaS, and is found to allow significant activation by CRP, both in vivo and in vitro, although full-length Rha S allowed somewhat greater CRP activation. Expand
Differences in the mechanism of the allosteric l‐rhamnose responses of the AraC/XylS family transcription activators RhaS and RhaR
TLDR
This work uses random mutagenesis to isolate RhaS and RhaR variants with enhanced activation in the absence of l‐rhamnose, and proposes separate allosteric mechanisms for the two proteins. Expand
The transcriptional activator of the bfp operon in EPEC (PerA) interacts with the RNA polymerase alpha subunit
TLDR
Results showed that PerA interacts with the alpha subunit of the RNAP polymerase and that it is necessary for the genetic and phenotypic expression of bfpA, an AraC/XylS-like regulator. Expand
ExsA Recruits RNA Polymerase to an Extended −10 Promoter by Contacting Region 4.2 of Sigma-70
TLDR
The collective data suggest a model in which ExsA compensates for the lack of a -35 hexamer by interacting with region 4.2 of sigma(70) to recruit RNAP to the promoter and several amino acids were found to contribute to the interaction. Expand
A basic/hydrophobic cleft of the T4 activator MotA interacts with the C‐terminus of E. coli σ70 to activate middle gene transcription
TLDR
NMR chemical shift analysis indicates that MotA uses a ‘basic/hydrophobic’ cleft to interact with the C‐terminus of AsiA‐remodelled σ70, but MotA does not interact with AsaA itself, which supports accumulated evidence indicating that ‘σ appropriation’ by MotA and Asi a uses a fundamentally different mechanism to activate transcription. Expand
Roles of Effectors in XylS-Dependent Transcription Activation: Intramolecular Domain Derepression and DNA Binding
TLDR
XylS showed specific 3MB-independent binding to its target operator, which became strictly 3MB dependent in a dimerization-defective mutant, and it was demonstrated that the N-terminal domain of the protein can make linker-independent interactions with the C-terminals and inhibit its capacity to bind DNA. Expand
H-NS Binding and Repression of the ctx Promoter in Vibrio cholerae
TLDR
It is demonstrated that transcriptional regulation of ctx and tcpA by H-NS and ToxT is mechanistically distinct, and this may lead to important differences in the expression of these coregulated genes. Expand
Transcription activation by the siderophore sensor Btr is mediated by ligand-dependent stimulation of promoter clearance
TLDR
It is reported that Bacillus subtilis Btr, a member of the AraC family of activators, functions principally as a ligand-dependent activator of promoter clearance, while having only modest effects on either RNAP promoter association or the production of abortive transcripts. Expand

Genetic Evidence that Transcription Activation by RhaS Involves Specific Amino Acid Contacts with Sigma 70
TLDR
This work provides the first evidence for a specific residue within an AraC/XylS family protein that may contact sigma(70), which molecular modeling suggests is located in very close proximity to RhaS D241. Expand
Interdependence of Activation at rhaSR by Cyclic AMP Receptor Protein, the RNA Polymerase Alpha Subunit C-Terminal Domain, and RhaR
TLDR
It is found that DNA-contacting residues in alpha-CTD are required for full activation, and the effects of alanine substitutions in CRP activating regions 1 and 2, overexpression of a truncated version of alpha (alpha-Delta235), and alanin substitutions throughout alpha- CTD are tested. Expand
Amino Acid-DNA Contacts by RhaS: an AraC Family Transcription Activator
TLDR
Alignment with the recently crystallized MarA protein suggest that both RhaS motifs are likely helix-turn-helix DNA-binding motifs. Expand
A regulatory cascade in the induction of rhaBAD.
TLDR
Quantitative primer extension analysis showed that induction of both the rhaBAD and rhaSR messages was unusually slow, requiring 40 to 50 minutes to reach a steady-state level. Expand
Purification and properties of RhaR, the positive regulator of the L-rhamnose operons of Escherichia coli.
TLDR
The product of the RhaR gene, which regulates the level of mRNA produced from the four L-rhamnose-inducible promoters of the rhamnosed operon, has been hypersynthesized and purified by a two-column procedure and the equilibrium binding constants and kinetic constants have been determined under a variety of solution conditions. Expand
Positive regulation of the Escherichia coli L-rhamnose operon is mediated by the products of tandemly repeated regulatory genes.
TLDR
In-vivo dimethyl sulfate footprinting and DNase I footprinting indicate that the RhaR protein may bind to DNA elements upstream from its RNA polymerase binding site. Expand
Arac/XylS family of transcriptional regulators
The ArC/XylS family of prokaryotic positive transcriptional regulators includes more than 100 proteins and polypeptides derived from open reading frames translated from DNA sequences. Members of thisExpand
Identification of a contact site for different transcription activators in region 4 of the Escherichia coli RNA polymerase sigma70 subunit.
TLDR
Using a series of 16 alanine-substitution mutations, residues in a narrow region of Escherichia coli sigma70 are involved in transcription activation by a mutationally altered CRP derivative, FNR and AraC. Expand
Protein-protein and protein-DNA interactions of σ70 region 4 involved in transcription activation by λcI
TLDR
These findings suggest that the R588 side-chain has a dual function at PRM, facilitating the interaction of region 4 with the promoter −35 element and participating directly in the protein–protein interaction with λcI. Expand
DNA-dependent renaturation of an insoluble DNA binding protein. Identification of the RhaS binding site at rhaBAD.
TLDR
It is found that active RhaS protein could be recovered only if the renaturation reaction was performed in the presence of DNA, and the recovery of DNA-binding activity from the related AraC protein, after denaturation in urea, was dependent upon added DNA. Expand
