PhoP-PhoQ-regulated loci are required for enhanced bile resistance in Salmonella spp. (1/1176)

As enteric pathogens, Salmonella spp. are resistant to the actions of bile. Salmonella typhimurium and Salmonella typhi strains were examined to better define the bile resistance phenotype. The MICs of bile for wild-type S. typhimurium and S. typhi were 18 and 12%, respectively, and pretreatment of log-phase S. typhimurium with 15% bile dramatically increased bile resistance. Mutant strains of S. typhimurium and S. typhi lacking the virulence regulator PhoP-PhoQ were killed at significantly lower bile concentrations than wild-type strains, while strains with constitutively active PhoP were able to survive prolonged incubation with bile at concentrations of >60%. PhoP-PhoQ was shown to mediate resistance specifically to the bile components deoxycholate and conjugated forms of chenodeoxycholate, and the protective effect was not generalized to other membrane-active agents. Growth of both S. typhimurium and S. typhi in bile and in deoxycholate resulted in the induction or repression of a number of proteins, many of which appeared identical to PhoP-PhoQ-activated or -repressed products. The PhoP-PhoQ regulon was not induced by bile, nor did any of the 21 PhoP-activated or -repressed genes tested play a role in bile resistance. However, of the PhoP-activated or -repressed genes tested, two (prgC and prgH) were transcriptionally repressed by bile in the medium independent of PhoP-PhoQ. These data suggest that salmonellae can sense and respond to bile to increase resistance and that this response likely includes proteins that are members of the PhoP regulon. These bile- and PhoP-PhoQ-regulated products may play an important role in the survival of Salmonella spp. in the intestine or gallbladder.  (+info)

Induction of the soxRS regulon of Escherichia coli by superoxide. (2/1176)

The soxRS regulon orchestrates a multifaceted defense against oxidative stress, by inducing the transcription of approximately 15 genes. The induction of this regulon by redox agents, known to mediate O-2 production, led to the view that O-2 is one signal to which it responds. However, redox cycling agents deplete cellular reductants while producing O-2, and one may question whether the regulon responds to the depletion of some cytoplasmic reductant or to O-2, or both. We demonstrate that raising [O-2] by mutational deletion of superoxide dismutases and/or by addition of paraquat, both under aerobic conditions, causes induction of a member of the soxRS regulon and that a mutational defect in soxRS eliminates that induction. This establishes that O-2, directly or indirectly, can cause induction of this defensive regulon.  (+info)

Mutational analysis of the phoD promoter in Bacillus subtilis: implications for PhoP binding and promoter activation of Pho regulon promoters. (3/1176)

The PhoP-PhoR two-component regulatory system controls the phosphate deficiency response in B. subtilis. A number of Pho regulon genes which require PhoP approximately P for activation or repression have been identified. The studies reported here were initiated to understand the PhoP-DNA interaction necessary for Pho promoter regulation. The regulatory region of phoD was characterized in detail using oligo-directed mutagenesis, DNase I footprinting, and in vivo transcription assays. These data reveal basic principles of PhoP binding relevant to PhoP's interaction with other Pho regulon promoters. Our results show that: (i) a dimer of PhoP approximately P is able to bind two consensus repeats in a stable fashion; (ii) PhoP binding is highly cooperative within the core promoter region, which is located from -66 to -17 on the coding strand and contains four TT(A/T/C)ACA-like repeats; (iii) specific bases comprising the TT(A/T/C)ACA consensus are essential for transcriptional activation, but the specific base pairs of the intervening sequences separating the consensus repeats are not important for either PhoP binding or promoter activation; (iv) the spacing between two consensus repeats within a putative dimer binding site in the core region is important for both PhoP binding and promoter activation; (v) the exact spacing between two dimer binding sites within the core region is important for promoter activation but less so for PhoP binding affinity, as long as the repeats are on the same face of the helix; and (vi) the 5' secondary binding region is important for coordinated PhoP binding to the core binding region, making it nearly essential for promoter activation.  (+info)

Nitroreductase A is regulated as a member of the soxRS regulon of Escherichia coli. (4/1176)

Nitroreductase A catalyzes the divalent reduction of nitro compounds, quinones, and dyes by NADPH. In this paper, nitroreductase A is induced in Escherichia coli by exposure to paraquat in a manner that depends on the expression of soxR. Nitroreductase activity was only slightly induced by paraquat in a strain bearing a mutational defect in the gene encoding nitroreductase A, but it was approximately 3-fold induced in the parental strain. Nitroreductase A thus appears to be a member of the soxRS regulon and probably contributes to the defenses against oxidative stress by minimizing the redox cycling attendant upon the univalent reduction of nitro compounds, quinones, and dyes.  (+info)

Acarbose, a pseudooligosaccharide, is transported but not metabolized by the maltose-maltodextrin system of Escherichia coli. (5/1176)

The pseudooligosaccharide acarbose is a potent inhibitor of amylases, glucosidases, and cyclodextrin glycosyltransferase and is clinically used for the treatment of so-called type II or insulin-independent diabetes. The compound consists of an unsaturated aminocyclitol, a deoxyhexose, and a maltose. The unsaturated aminocyclitol moiety (also called valienamine) is primarily responsible for the inhibition of glucosidases. Due to its structural similarity to maltotetraose, we have investigated whether acarbose is recognized as a substrate by the maltose/maltodextrin system of Escherichia coli. Acarbose at millimolar concentrations specifically affected the growth of E. coli K-12 on maltose as the sole source of carbon and energy. Uptake of radiolabeled maltose was competitively inhibited by acarbose, with a Ki of 1.1 microM. Maltose-grown cells transported radiolabeled acarbose, indicating that the compound is recognized as a substrate. Studying the interaction of acarbose with purified maltoporin in black lipid membranes revealed that the kinetics of acarbose binding to LamB is asymmetric. The on-rate of acarbose is approximately 30 times lower when the molecule enters the pore from the extracellular side than when it enters from the periplasmic side. Acarbose could not be utilized as a carbon source since the compound alone was not a substrate of amylomaltase (MalQ) and was only poorly attacked by maltodextrin glucosidase (MalZ).  (+info)

In vivo transcription of the Escherichia coli oxyR regulon as a function of growth phase and in response to oxidative stress. (6/1176)

Simultaneous expression of seven genes in Escherichia coli was measured by a reverse transcription-multiplex PCR fluorescence procedure. Genes studied were (i) oxyR (transcriptional regulator); (ii) katG, dps, gorA, and ahpCF (controlled by OxyR); (iii) sodA (controlled by SoxRS); and (iv) trxA (not related to OxyR or SoxRS). Except for trxA, transcription of all genes was activated during the course of growth of wild-type bacteria, though notable variations were observed with respect to both the time and extent of activation. Whereas oxyR, katG, dps, and gorA were activated during exponential growth, ahpCF and sodA were stimulated in stationary phase. Maximal induction ranged from 4.6- to 86.5-fold, for gorA and dps, respectively. Treatment with H2O2 stimulated expression of the genes (katG, dps, ahpCF, and gorA) previously identified as members of the OxyR regulon, except for oxyR itself. Induction by H2O2 was a remarkably rapid and reversible process that took place in an OxyR-dependent and sigmaS-independent manner. NaCl induced expression of the genes controlled by OxyR, including the oxyR locus. This transcriptional up-regulation was preserved in a strain with the DeltaoxyR::kan mutation, but it was abolished (ahpCF) or significantly reduced (oxyR and dps) in a strain with the rpoS::Tn10 mutation, potentially reflecting positive transcriptional regulation of the oxyR regulon by sigmaS. Expression of trxA was not increased either by H2O2 stress or by a shift to high-osmolarity conditions.  (+info)

Identification and transcriptional analysis of new members of the sigmaB regulon in Bacillus subtilis. (7/1176)

Bacillus subtilis responds to various stimuli (heat, ethanol and salt stress, energy starvation) with the induction of general stress proteins (GSPs). Most of them belong to the stress and stationary-phase regulon controlled by the alternative sigma factor sigmaB. The majority of sigmaB-dependent proteins are thought to provide a precautionary general stress resistance in stressed or starved cells. In this report, the identification and transcriptional analysis of nine new members of the sigmaB regulon are described. The biochemical function was not determined for any of the proteins encoded by the nine new sigmaB-dependent stress genes, however, similarities to proteins in the databases allowed a distinction between proteins with putative (i-iv) and unknown (v) function. The putative functions of BmrU, YcdF, YdaD, YdaP, YhdN and YocK underline the suggested protective role of sigmaB-dependent GSPs and also elucidate new areas where sigmaB might play an important role. (i) The finding that the bmrUR operon is under sigmaB control indicates that the elimination of multidrug compounds might be a new function in multiple stress resistance. (ii) YcdF and YdaD resemble NAD(P)-dependent dehydrogenases. Both proteins could be involved in the generation of NAD(P)H and therefore in the maintenance of the intracellular redox balance under stress. (iii) The ydaP gene might belong to the increasing number of sigmaB-dependent genes whose orthologues are under the control of sigmas in Escherichia coli, indicating that both regulons may fulfil similar functions. (iv) YhdN shows weak similarities to potassium ion channel proteins and YocK shows resemblance to the DnaK suppressor protein DksA. (v) Three new sigmaB-dependent genes (ydaE, ydaG and yfkM) encoding proteins with still unknown functions were also described. Further analyses of corresponding mutants might allow a first prediction of their function within the framework of the general stress regulon.  (+info)

A HilA-independent pathway to Salmonella typhimurium invasion gene transcription. (8/1176)

Salmonella typhimurium invasion of nonphagocytic cells requires the expression of a type III secretion system (TTSS) encoded within Salmonella pathogenicity island 1 (SPI1). TTSS gene transcription is activated in response to environmental signals and requires transcriptional regulators encoded within (HilA) and outside (SirA) SPI1. Two unique loci, sirB and sirC, which contribute to SPI1 gene transcription were defined. sirC is an SPI1-encoded transcription factor of the AraC family that contributes to the invasive phenotype. sirB is required for maximal expression of sirC and consists of two open reading frames located near kdsA, a gene involved in lipopolysaccharide biosynthesis. sirC expression, unlike expression of other SPI1 genes, does not require HilA. Overexpression of sirC or sirA restores expression of a subset of SPI1 genes, including invF and sspC, in the absence of HilA. These data define roles for SirC and SirA as part of a HilA-independent pathway to SPI1 gene expression. We postulate that HilA-independent activation of inv expression is important for efficient assembly and function of the SPI1 TTSS.  (+info)

Gene Expression: RNA regulonsGene Expression: RNA regulons
Many other examples can be found in this review by Jack Keene. I dont think Ive seen an example of this yet, but given the slight wobble in microRNA specificity, one could imagine a single microRNA regulating a whole set of genes. Also, most interesting for my neuro-tastes is the recent report from the Moore lab showing that the immediate-early gene implicated in neuronal homeostasis, Arc, may be part of a regulon defined by introns in the 3UTR. The mechanism is just too clever but requires an explication on the pioneer round of translation. Basically the cell tricks itself into thinking it made a funky RNA and destroys it after one round of synthesis. The other RNAs regulated in this path in neurons must have opposing effects to Arc though because knocking down this negative regulation pathway led to increased excitability (increased Arc reduces neuronal excitability). This raises a more general question. The idea of RNA regulons is nice, but how much can you predict knowing that your gene ...

Abstract: Approximately 1.7 billion population of the world contain latent Mycobacterium tuberculosis (Mtb) with a substantial risk of progression to clinical outcome. Containment of seed beds of Mtb is essential to eliminate tuberculosis completely in high burden settings like India. Hence, there is an urgent need for the development of putative serological markers for detection or vaccine candidates to prevent latent tuberculosis infection (LTBI). DosR regulon antigens of Mtb might serve as attractive targets for LTBI diagnosis or vaccine development as they are specifically expressed and are up-regulated during latent phase. In this study, we investigated the role of Rv2004c, a member of DosR regulon (exclusive to Mtb complex), in host pathogen interactions and its immunogenic potential in LTBI, active TB and healthy control cohorts. Rv2004c elicited strong antibody response in individuals with LTBI compared to active TB patients and healthy cohorts. Recombinant Rv2004c induced pro-inflammatory

Microbial biofilm formation is thought of as a developmental pathway, whereby cells progress through environmentally regulated and temporally distinct stages during transition from free-swimming lifestyles to members of a structured surface-attached consortium. The focus of my doctoral studies has been to understand how environmental cues are sensed by P. fluorescens and integrated with mechanisms to regulate an important step in biofilm formation, the transition to committed association with the surface. Low levels of extracellular inorganic phosphate (P i ) were shown to inhibit stable surface attachment by P. fluorescens. Activation of the Pho regulon in P i -limiting conditions was shown to be both necessary and sufficient for inhibition of biofilm formation. The protein product of the Pho regulon gene rapA cleaves the intracellular signaling molecule c-di-GMP. Reductions in the levels of c-di-GMP were shown to inhibit both secretion and localization of LapA to the outer membrane. LapA is a ...

Escherichia coli responds to the redox stress imposed by superoxide-generating agents such as paraquat by activating the synthesis of as many as 80 polypeptides. Expression of a key group of these inducible proteins is controlled at the transcriptional level by the soxRS locus (the soxRS regulon). A two-stage control system was hypothesized for soxRS, in which an intracellular redox signal would trigger the SoxR protein as a transcriptional activator of the soxS gene and the resulting increased levels of SoxS protein would activate transcription of the various soxRS regulon genes (B. Demple and C.F. Amábile Cuevas, Cell 67:837-839, 1990). We have constructed operon fusions of the E. coli lac genes to the soxS promoter to monitor soxS transcription. Expression from the soxS promoter is strongly inducible by paraquat in a manner strictly dependent on a functional soxR gene. Several other superoxide-generating agents also trigger soxR(+)-dependent soxS expression, and the inductions by paraquat ...

SMART: Secondary literature for CXC domainSMART: Secondary literature for CXC domain
The kil-kor regulon of the self-transmissible, broad-host-range plasmid RK2 is a unique network with eight coregulated operons. Among the genes encoded by the kil-kor regulon are trfA, which encodes the replication initiator, and several kil loci (kilA, kilB, kilC, and kilE), each of which is lethal to the host cell in the absence of appropriate negative regulatory elements encoded by the korA, korB, korC, and korE determinants. We have proposed that the functions of the kil loci are related to RK2 maintenance or host range. Here, we report the nucleotide sequence of a 2.44-kb region that includes the lethal kilB determinant. We identified the first three genes of the kilB operon (designated klbA, klbB, and klbC), and we determined by deletion analysis that the host-lethal phenotype requires klbB. The predicted amino acid sequence of the 34,995-Da klbA product reveals a potential ATP-binding fold. The klbB product is predicted to be a membrane protein with a molecular mass of 15,012 Da with ...

The YvfTU Two-component System is involved in plcR expression in Bacillus cereusThe YvfTU Two-component System is involved in plcR expression in Bacillus cereus
Background. Most extracellular virulence factors produced by Bacillus cereus are regulated by the pleiotropic transcriptional activator PlcR. Among strains belonging to the B. cereus group, the plcR gene is always located in the vicinity of genes encoding the YvfTU two-component system. The putative role of YvfTU in the expression of the PlcR regulon was therefore investigated.. Results. Expression of the plcR gene was monitored using a transcriptional fusion with a lacZ reporter gene in a yvfTU mutant and in its B. cereus ATCC 14579 parental strain. Two hours after the onset of the stationary phase, a stage at which the PlcR regulon is highly expressed, the plcR expression in the yvfTU mutant was only 50% of that of its parental strain. In addition to the reduced plcR expression in the yvfTU mutant, a few members of the PlcR regulon showed a differential expression, as revealed by transcriptomic and proteomic analyses. The virulence of the yvfTU mutant in a Galleria mellonella insect model was ...

Bioconductor - RTNsurvivalBioconductor - RTNsurvival
Bioconductor version: Release (3.6) RTNsurvival is a tool for integrating regulons generated by the RTN package with survival information. For a given regulon, the 2-tailed GSEA approach computes a differential Enrichment Score (dES) for each individual sample, and the dES distribution of all samples is then used to assess the survival statistics for the cohort. There are two main survival analysis workflows: a Cox Proportional Hazards approach used to model regulons as predictors of survival time, and a Kaplan-Meier analysis assessing the stratification of a cohort based on the regulon activity. All plots can be fine-tuned to the users specifications.. Author: Clarice S. Groeneveld, Vinicius S. Chagas, Mauro A. A.

Cell Envelope Stress Response And Antimicrobial Resistance In Bacillus SubtilisCell Envelope Stress Response And Antimicrobial Resistance In Bacillus Subtilis
The cell envelope of bacteria is of pivotal importance for growth and survival, and hence it is often the target of antimicrobial compounds. One of the main components involved in CESRs are extracytoplasmic function (ECF) [sigma] factors. The genome of B. subtilis encodes for seven ECF [sigma] factors, [sigma]M, [sigma]W, [sigma]X, [sigma]Y, [sigma]V, [sigma]Z and [sigma]YlaC. Several studies have been conducted to understand the role that these ECF [sigma] factors play in CESR in B. subtilis, one of the challenges found is that they display significant redundancy within their regulons. In this study, we have performed an in depth analysis of one of the ECF [sigma] factors of B. subtilis, [sigma]V, which had been previously uncharacterized. We have described the regulon of [sigma]V, the role that it plays in lysozyme resistance, and provided evidence for a novel promoter element important for [sigma]V recognition. Additionally, we have studied the role that [sigma]M plays in moenomycin ...

Role of the Fur Regulon in Iron Transport in Bacillus subtilis | Journal of BacteriologyRole of the Fur Regulon in Iron Transport in Bacillus subtilis | Journal of Bacteriology
Iron is an essential nutrient for nearly all living organisms (1). Transport systems for the uptake of iron and iron-chelation complexes are therefore critical for growth (64). In many bacteria, the ferric uptake regulator (Fur) protein coordinates the expression of iron uptake and homeostasis pathways in response to available iron (1). For example, in Escherichia coli K-12 the Fur regulon includes genes for the biosynthesis and transport of the catechol siderophore enterobactin, the uptake of various hydroxamate siderophores, and a substrate-inducible ferric citrate uptake system (25, 45). In addition, Fur represses a small RNA, RyhB, that in turn negatively regulates the expression of iron-rich enzymes such as succinate dehydrogenase, fumarase, and aconitase (36). This allows the production of these enzymes to be activated in response to available iron.. The production of low-molecular-weight Fe(III) chelators (siderophores) enables microorganisms to efficiently scavenge iron even in aerobic ...

Background The expression of genes in Corynebacterium glutamicum, a Gram-positive non-pathogenic bacterium used mainly for the industrial production of amino acids, is regulated by seven different sigma factors of RNA polymerase, including the stress-responsive ECF-sigma factor SigH. The sigH gene is located in a gene cluster together with the rshA gene, putatively encoding an anti-sigma factor. The aim of this study was to analyze the transcriptional regulation of the sigH and rshA gene cluster and the effects of RshA on the SigH regulon, in order to refine the model describing the role of SigH and RshA during stress response. Results Transcription analyses revealed that the sigH gene and rshA gene are cotranscribed from four sigH housekeeping promoters in C. glutamicum. In addition, a SigH-controlled rshA promoter was found to only drive the transcription of the rshA gene. To test the role of the putative anti-sigma factor gene rshA under normal growth conditions, a C. glutamicum rshA deletion ...

The soil living, Gram-positive bacterium Bacillus subtilis is frequently exposed to a wide variety of stress and starvation conditions in its natural environment. In order to survive under these environmental and energy stresses, the bacterium acquired a general stress response mechanism mediated by the alternative sigma factor, SigB. A wide-variety of stress conditions such as environmental stress conditions like ethanol stress, heat stress, oxidative stress, osmotic stress or limitation of glucose, oxygen, phosphate etc.; and low temperature growth induce this SigB-dependent general stress response. Though much is known about the mechanisms of activation of this general stress response, the conditions that induce the SigB regulon and its general functions, the definition of the structure of the SigB regulon is not completely clear. The SigB-dependent general stress regulon has previously been characterized by proteomic approaches as well as DNA-array based expression studies. Genome-wide ...

Identification of the MBF1 heat-response regulon of Arabidopsis thaliana.Identification of the MBF1 heat-response regulon of Arabidopsis thaliana.
Brief periods of heat stress of even a few days can have a detrimental effect on yield production worldwide causing devastating economical and sociological impacts. Here we report on the identification of a new heat-response regulon in plants controlled by the multiprotein bridging factor 1c (MBF1c) protein of Arabidopsis thaliana. Members of the highly conserved MBF1 protein family function as non DNA-binding transcriptional co-activators involved in regulating metabolic and development pathways in different organisms from yeast to humans. Nonetheless, our studies suggest that MBF1c from Arabidopsis functions as a transcriptional regulator which binds DNA and controls the expression of 36 different transcripts during heat stress, including the important transcriptional regulator DRE-binding protein 2A (DREB2A), two heat shock transcription factors (HSFs), and several zinc finger proteins. We further identify CTAGA as a putative response element for MBF1c, demonstrate that the DNA-binding domain ...

Catalyzes the conversion of O-acetylserine to cysteine. Also acts as a sensor of cysteine availability in the signal transduction pathway modulating CymR activity. When cysteine is present, the pool of O-acetylserine (OAS) is low, which leads to the formation of a CymR-CysK complex and transcriptional repression of the CymR regulon occurs. In the absence of cysteine, the OAS pool is high and the CymR-CysK complex is mostly dissociated, leading to a faster dissociation of CymR from its DNA targets and the lifting of CymR-dependent repression ...

Comparative Proteomic Analysis of the PhoP Regulon in Salmonella enterica Serovar Typhi Versus TyphimuriumComparative Proteomic Analysis of the PhoP Regulon in Salmonella enterica Serovar Typhi Versus Typhimurium
Background: S. Typhi, a human-restricted Salmonella enterica serovar, causes a systemic intracellular infection in humans (typhoid fever). In comparison, S. Typhimurium causes gastroenteritis in humans, but causes a systemic typhoidal illness in mice. The PhoP regulon is a well studied two component (PhoP/Q) coordinately regulated network of genes whose expression is required for intracellular survival of S. enterica. Methodology/Principal Findings: Using high performance liquid chromatography mass spectrometry (HPLC-MS/MS), we examined the protein expression profiles of three sequenced S. enterica strains: S. Typhimurium LT2, S. Typhi CT18, and S. Typhi Ty2 in PhoP-inducing and non-inducing conditions in vitro and compared these results to profiles of \(phoP^−/Q^−\) mutants derived from S.

The bacterial cell envelope is the first and major line of defence against threats from the environment. It is an essential and vulnerable structure that gives the cell its shape and counteracts the high internal osmotic pressure. It also provides an important sensory interface and molecular sieve, mediating both information flow and controlled transport of solutes. The cell envelope is also the target for numerous antibiotics. Therefore, the monitoring and maintaining of cell envelope integrity in the presence of envelope perturbating agents and conditions is crucial for survival. In Bacillus subtilis a complex regulatory network, consisting of 7 signal transducing systems, orchestrates the cell envelope stress response. Two forms of regulatory systems can be found: ECF-sigma factors and two component systems (TCS). One of these TCS is the LiaRS system that responds to cell wall antibiotics that interfere with the undecaprenol cycle and to perturbation of the cytoplasmic me! mbrane. It is ...

The general stress response comprises approximately 200 genes and is driven by the alternative sigma factor SigB. Besides the process of sporulation with approximately 500 involved gene products under initial control of Spo0A are the two most significant and extensive cellular responses that can be observed in B. subtilis. The general stress response provides vegetative growing as well as non-growing and non-sporulating cells with a comprehensive cross-protective and preventive multiple stress resistance to various hostile environmental conditions. In contrast, the endospore is the most resistant but also dormant cell type produced by B. subtilis. The scope of this study was the identification of regulatory cascades driven by the general stress response sigma factor SigB to further elucidate the structure and function of the general stress regulon itself and to uncover potential intersections between the SigB response and other major developmental programs in the regulatory network of B. ...

ASMscience | The Cpx Envelope StressASMscience | The Cpx Envelope Stress
This chapter summarizes studies that led to identification and characterization of the Cpx envelope stress response and highlights recent work that hints at a diverse range of Cpx-influenced cellular phenotypes. Silverman and colleagues provided the kernels for our current understanding of the Cpx envelope stress response. The Cpx envelope stress response is regulated by a typical two-component regulatory system. In addition to functioning as an activator and a repressor, a new role for CpxR~P in transcription has recently been put forth, that of potentiator. Researchers have shown by microarray analysis of biofilm and planktonic populations of cells that the Cpx-regulated genes cpxP and spy were highly up-regulated in biofilms and that cpxP and cpxR mutants formed biofilms with reduced mass and substrate coverage. It has been shown that CpxR homologues in Legionella pneumophila and Yersinia enterocolitica are likely involved in transcription of the icm-dot genes encoding the type IV secretion system

During the production of wine and beer, the yeast Saccharomyces cerevisiae can encounter an environment that is deficient in zinc, resulting in a sluggish or a stuck ferment. It has been shown that the Zap1p-transcription factor induces the expression of a regulon in response to zinc deficiency; however, it was evident that a separate regulon was also activated during zinc deficiency in a Zap1p-independent manner. This study discovered the Msn2p and Msn4p (Msn2/4p) transcriptional activator proteins to be an additional control mechanism inducing the stress response during zinc deficiency. Promoter sequence analysis identified the stress response element (STRE) motif, recognized by Msn2/4p, and was significantly enriched in the promoters of genes induced by zinc deficiency. An investigation using genome-wide analyses revealed a distinct regulon consisting of STREcontaining genes whose zinc-responsive expression was abolished in an msn2 msn4 double mutant. An STRE-driven lacZ reporter ...

The exoenzyme S regulon is a set of coordinately regulated virulence genes of Pseudomonas aeruginosa. Proteins encoded by the regulon include a type III secretion and translocation apparatus, regulators of gene expression, and effector proteins. The effector proteins include two enzymes with ADP-ribosyltransferase activity (ExoS and ExoT) and an acute cytotoxin (ExoU). In this study, we identified ExoY as a fourth effector protein of the regulon. ExoY is homologous to the extracellular adenylate cyclases of Bordetella pertussis (CyaA) and Bacillus anthracis (EF). The homology among the three adenylate cyclases is limited to two short regions, one of which possesses an ATP-binding motif. In assays for adenylate cyclase activity, recombinant ExoY (rExoY) catalyzed the formation of cAMP with a specific activity similar to the basal activity of CyaA. In contrast to CyaA and EF, rExoY activity was not stimulated or activated by calmodulin. A 500-fold stimulation of activity was detected following the ...

Phosphate plays an essential role in nearly all metabolic, catabolic, and signaling events within virtually all living organisms. As such, the trafficking of phosphate anions is an immensely important function, yet the specific mechanism utilized to transport inorganic phosphate molecules across a lipid bilayer remains unclear. The Gram negative bacterial cell utilizes a double membrane system and employs a plethora of channels that can be constitutive or specifically expressed in its outer membrane (OM) in response to various environmental conditions. Most bacteria, including Pseudomonas react to environmental conditions of low phosphate by turning on a gene regulon leading to the expression of a number of phosphate trafficking proteins (Figure 2). This regulation is mediated by regulatory proteins anchored in the inner membrane (PhoR), that sense phosphate levels through an as yet uncharacterized interaction with the inner membrane transport complex.. ...
