A segment of cold shock protein directs the folding of a combinatorial protein. (1/35)

It has been suggested that protein domains evolved by the non-homologous recombination of building blocks of subdomain size. In earlier work we attempted to recapitulate domain evolution in vitro. We took a polypeptide segment comprising three beta-strands in the monomeric, five-stranded beta-barrel cold shock protein (CspA) of Escherichia coli as a building block. This segment corresponds to a complete exon in homologous eukaryotic proteins and includes residues that nucleate folding in CspA. We recombined this segment at random with fragments of natural proteins and succeeded in generating a range of folded chimaeric proteins. We now present the crystal structure of one such combinatorial protein, 1b11, a 103-residue polypeptide that includes segments from CspA and the S1 domain of the 30S ribosomal subunit of E. coli. The structure reveals a segment-swapped, six-stranded beta-barrel of unique architecture that assembles to a tetramer. Surprisingly, the CspA segment retains its structural identity in 1b11, recapitulating its original fold and deforming the structure of the S1 segment as necessary to complete a barrel. Our work provides structural evidence that (i) random shuffling of nonhomologous polypeptide segments can lead to folded proteins and unique architectures, (ii) many structural features of the segments are retained, and (iii) some segments can act as templates around which the rest of the protein folds.  (+info)

Gene expression regulation by the Curli activator CsgD protein: modulation of cellulose biosynthesis and control of negative determinants for microbial adhesion. (2/35)

Curli fibers, encoded by the csgBAC genes, promote biofilm formation in Escherichia coli and other enterobacteria. Curli production is dependent on the CsgD transcription activator, which also promotes cellulose biosynthesis. In this study, we investigated the effects of CsgD expression from a weak constitutive promoter in the biofilm formation-deficient PHL565 strain of E. coli. We found that despite its function as a transcription activator, the CsgD protein is localized in the cytoplasmic membrane. Constitutive CsgD expression promotes biofilm formation by PHL565 and activates transcription from the csgBAC promoter; however, csgBAC expression remains dependent on temperature and the growth medium. Constitutive expression of the CsgD protein results in altered transcription patterns for at least 24 novel genes, in addition to the previously identified CsgD-dependent genes. The cspA and fecR genes, encoding regulatory proteins responding to cold shock and to iron, respectively, and yoaD, encoding a putative negative regulator of cellulose biosynthesis, were found to be some of the novel CsgD-regulated genes. Consistent with the predicted functional role, increased expression of the yoaD gene negatively affects cell aggregation, while yoaD inactivation results in stimulation of cell aggregation and leads to increased cellulose production. Inactivation of fecR results in significant increases in both cell aggregation and biofilm formation, while the effects of cspA are not as strong in the conditions tested. Our results indicate that CsgD can modulate cellulose biosynthesis through activation of the yoaD gene. In addition, the positive effect of CsgD on biofilm formation might be enhanced by repression of the fecR gene.  (+info)

Control and regulation of the cellular responses to cold shock: the responses in yeast and mammalian systems. (3/35)

Although the cold-shock response has now been studied in a number of different organisms for several decades, it is only in the last few years that we have begun to understand the molecular mechanisms that govern adaptation to cold stress. Notably, all organisms from prokaryotes to plants and higher eukaryotes respond to cold shock in a comparatively similar manner. The general response of cells to cold stress is the elite and rapid overexpression of a small group of proteins, the so-called CSPs (cold-shock proteins). The most well characterized CSP is CspA, the major CSP expressed in Escherichia coli upon temperature downshift. More recently, a number of reports have shown that exposing yeast or mammalian cells to sub-physiological temperatures (<30 or <37 degrees C respectively) invokes a co-ordinated cellular response involving modulation of transcription, translation, metabolism, the cell cycle and the cell cytoskeleton. In the present review, we summarize the regulation and role of cold-shock genes and proteins in the adaptive response upon decreased temperature with particular reference to yeast and in vitro cultured mammalian cells. Finally, we present an integrated model for the co-ordinated responses required to maintain the viability and integrity of mammalian cells upon mild hypothermic cold shock.  (+info)

Global effects of homocysteine on transcription in Escherichia coli: induction of the gene for the major cold-shock protein, CspA. (4/35)

Homocysteine (Hcy) is a thiol-containing amino acid that is considered to be medically important because it is linked to the development of several life-threatening diseases in humans, including cardiovascular disease and stroke. It inhibits the growth of Escherichia coli when supplied in the growth medium. Growth inhibition is believed to arise as a result of partial starvation for isoleucine, which occurs because Hcy perturbs the biosynthesis of this amino acid. This study attempted to further elucidate the inhibitory mode of action of Hcy by examining the impact of exogenously supplied Hcy on the transcriptome. Using gene macroarrays the transcript levels corresponding to 68 genes were found to be reproducibly altered in the presence of 0.5 mM Hcy. Of these genes, the biggest functional groups affected were those involved in translation (25 genes) and in amino acid metabolism (19 genes). Genes involved in protection against oxidative stress were repressed in Hcy-treated cells and this correlated with a decrease in catalase activity. The gene showing the strongest induction by Hcy was cspA, which encodes the major cold-shock protein CspA. RT-PCR and reporter fusion experiments confirmed that cspA was induced by Hcy. Induction of cspA by Hcy was not caused by nutritional upshift, a stimulus known to induce CspA expression, nor was it dependent on the presence of a functional CspA protein. The induction of cspA by Hcy was suppressed when isoleucine was included in the growth medium. These data suggest that the induction of CspA expression in the presence of Hcy occurs because of a limitation for isoleucine. The possibility that Hcy-induced cspA expression is triggered by translational stalling that occurs when the cells are limited for isoleucine is discussed.  (+info)

Cold shock domain proteins and glycine-rich RNA-binding proteins from Arabidopsis thaliana can promote the cold adaptation process in Escherichia coli. (5/35)

Despite the fact that cold shock domain proteins (CSDPs) and glycine-rich RNA-binding proteins (GRPs) have been implicated to play a role during the cold adaptation process, their importance and function in eukaryotes, including plants, are largely unknown. To understand the functional role of plant CSDPs and GRPs in the cold response, two CSDPs (CSDP1 and CSDP2) and three GRPs (GRP2, GRP4 and GRP7) from Arabidopsis thaliana were investigated. Heterologous expression of CSDP1 or GRP7 complemented the cold sensitivity of BX04 mutant Escherichia coli that lack four cold shock proteins (CSPs) and is highly sensitive to cold stress, and resulted in better survival rate than control cells during incubation at low temperature. In contrast, CSDP2 and GRP4 had very little ability. Selective evolution of ligand by exponential enrichment (SELEX) revealed that GRP7 does not recognize specific RNAs but binds preferentially to G-rich RNA sequences. CSDP1 and GRP7 had DNA melting activity, and enhanced RNase activity. In contrast, CSDP2 and GRP4 had no DNA melting activity and did not enhance RNAase activity. Together, these results indicate that CSDPs and GRPs help E.coli grow and survive better during cold shock, and strongly imply that CSDP1 and GRP7 exhibit RNA chaperone activity during the cold adaptation process.  (+info)

Bacterial toxicity of potassium tellurite: unveiling an ancient enigma. (6/35)

Biochemical, genetic, enzymatic and molecular approaches were used to demonstrate, for the first time, that tellurite (TeO(3) (2-)) toxicity in E. coli involves superoxide formation. This radical is derived, at least in part, from enzymatic TeO(3) (2-) reduction. This conclusion is supported by the following observations made in K(2)TeO(3)-treated E. coli BW25113: i) induction of the ibpA gene encoding for the small heat shock protein IbpA, which has been associated with resistance to superoxide, ii) increase of cytoplasmic reactive oxygen species (ROS) as determined with ROS-specific probe 2'7'-dichlorodihydrofluorescein diacetate (H(2)DCFDA), iii) increase of carbonyl content in cellular proteins, iv) increase in the generation of thiobarbituric acid-reactive substances (TBARs), v) inactivation of oxidative stress-sensitive [Fe-S] enzymes such as aconitase, vi) increase of superoxide dismutase (SOD) activity, vii) increase of sodA, sodB and soxS mRNA transcription, and viii) generation of superoxide radical during in vitro enzymatic reduction of potassium tellurite.  (+info)

Role of RNA structure and susceptibility to RNase E in regulation of a cold shock mRNA, cspA mRNA. (7/35)

Degradation of the cspA mRNA in vivo is very rapid at temperatures greater than 30 degrees C and is moderately dependent on RNase E. Investigations in vitro show that degradosomes prepared from normal or cold-shocked cultures cleave the cspA mRNA preferentially at a single site in vitro between two stem-loops approximately 24 residues 3' to the termination codon and approximately 31 residues from the 3' end. The site of cleavage is independent of the temperature and largely independent of the phosphorylation status of the 5' end of cspA mRNA. A 5' stem-loop, potential occlusion of the initiation and termination codons, temperature-dependent translational efficiency, and the position of the RNase E cleavage site can explain the differential stability of the cspA mRNA.  (+info)

Dimorphic aggregation behavior of a fusion polypeptide incorporating a stable protein domain (EGFP) with an amyloidogenic sequence (retroCspA). (8/35)


The cold shock domain (CSD) is a nucleic acid binding domain that is widely conserved from bacteria to higher plants and animals. In Escherichia coli, cold shock proteins (CSPs) are composed solely of a CSD and function as RNA chaperones that destabilize RNA secondary structures. Cellular RNAs tend to be folded into unfavorable structures under low temperature conditions, and RNA chaperones resolve these structures, recovering functionality of the RNAs. CSP functions are associated mainly with cold adaptation, but they are also involved in other biological processes under normal growth conditions. Eukaryotic CSD proteins contain auxiliary domains in addition to the CSD and regulate many biological processes such as development and stress tolerance. In plants, it has been demonstrated that CSD proteins play essential roles in acquiring freezing tolerance. In addition, it has been suggested that some plant CSD proteins regulate embryo development, flowering time and fruit development. In this review, we
RNA can typically fold into several isoenergetic structures, giving place to misfolded and non-functional structures. It is known that proteins can assist in RNA folding by two different mechanisms: binding and stabilizing specific structures, or by what is called RNA chaperone activity (RCA), an activity that accelerates folding through the resolution of misfolded structures or inhibition of their formation. Therefore one goal is to gain insight into RNA chaperone function on an atomic level. We use CspA as a model of RNA chaperone. CspA is the major cold shock protein in E. coli. It is a 70 residues protein that serves to induce adaptation to cold shock conditions (10-15°). Previous studies in our group on CspA dynamics showed that the protein is 1% unfolded at 32°C (M. Tollinger, unpublished results), it has single-stranded nucleic acid binding capacity. It is supposed to act as transcriptional anti-terminator for cold shock genes. We have already determined the solution structure of CspA ...

The p-value tells us whether or not a genes expression changes significantly but it is hard to know if that was due to cold shock or any other factor. The p-value of the profile gives us the significance of a particular group of genes, which should give us a better idea of which group of genes responded to cold shock, and get rid of some the possible random genes that were changed. The gene ontology p-value furthers specifies which gene could be affected by cold shock together by grouping the genes with their specific transcription factors. Each p-value allows us to narrow in on genes that are related to each other and helps to identify which genes were changed significantly, specifically due to cold shock ...

Cold shock proteins (Csps) are multifunctional nucleic acid binding proteins used to regulate a wide range of gene expression responses in bacteria. We report here that Csps regulate the production of the pore-forming cytolysin listeriolysin (LLO) and hemolysis phenotypes in Listeria monocytogenes. A triple csp gene deletion mutant incapable of producing any Csps, as well as double csp gene deletion mutants only producing either CspA or CspD, caused less hemolysis and produced lower LLO concentration. On the other hand, another double csp gene deletion mutant that produces CspB retained hemolysis and LLO production levels that are similar to the parental wild-type strain. Transcription analysis showed that in absence of all three csp genes or cspB alone, L. monocytogenes cells have decreased levels of hly gene transcripts, which code for the synthesis of LLO proteins. A comparative examination of mRNA stability showed that hly transcripts were more rapidly degraded in L. monocytogenes triple csp ...
The expression of genes for cold-shock proteins is proposed to be regulated primarily at the post-transcriptional level by increase of mRNA stability after transition to low temperatures. Destabilization of the Escherichia coli cold-induced cspA transcript at 37 °C as well as stabilization upon cold shock is known to depend on the unusually long (159 nt) 5′-untranslated region. Determination of the cspA mRNA 5′-end from Rhodobacter capsulatus revealed a shorter distance between the start of transcription and the start codon for translation. The cspA mRNA of R. capsulatus was shown to be stabilized at low temperatures to a greater extent than other investigated transcripts. To address the mechanism of decay of the cspA transcript, it was incubated with purified degradosome of R. capsulatus. Endoribonucleolytic in vitro cleavage in the 5′-untranslated region as reported for the cspA transcript of E. coli in vivo was not observed. Instead, the data indicated that the cspA mRNA decay in R. capsulatus
This 20-page report explains how cold shock is a type of hormesis, which is a description of a type of stress that, in the right doses, is enough to shock the body and kick off adaptive processes and response mechanisms that are hardwired into our genes, and, once on, are able to create a resilience that actually exceeds what was needed to counter the initial stimuli. Rhonda discusses how cold exposure increases norepinephrine up to 5-fold in the brain and what the temperature and duration needed to do this are, how norepinephrine has an effect on mood, vigilance, focus, and attention, how cold exposure increases cold shock proteins including one in the brain that repairs damaged synapses and in muscle prevents atrophy, how cold-induced norepinephrine lowers inflammation and pain by decreasing the levels of 3 inflammatory mediators, how chronic cold shock may increase immune cell numbers and particularly a type of immune cell that kills cancer cells, how cold exposure increases metabolic rate, ...
Cold shock of JH642 cells in the absence of an isoleucine supply showed a decrease in viable cell number that corresponds to the decrease in OD. These cultures show an increasing absorption after more than 48 h of cold shock, with a concomitant increase in cell number (data not shown). Repeating cold shock with these cultures (i.e., diluting the cells in fresh medium, growing them at 37°C, and performing a new cold shock experiment) revealed the same growth pattern as seen before with a cold-sensitive phenotype (data not shown). Therefore the occurrence of spontaneous mutation as a putative reason for this phenomenon is not likely. As the decrease in OD and viable cell number after 18 h of cold shock indicate, a large number of cells might lyse, delivering a reasonable amount of free isoleucine and threonine into the medium that is beneficial for viable cells to adapt and restart slow growth. This scenario was corroborated by a fatty acid analysis, where these cell cultures revealed a fatty ...
Csp family proteins have previously been linked to regulation of both normal growth and stress adaptation processes against cold and nutrient starvation as well as to promotion of survival stationary-phase cells in some organisms (13-15, 41, 42). In cold-adapted L. monocytogenes cells, the induction of Csp-like proteins, as well as cspA gene transcripts, was previously documented (5, 40). The current study was conducted in order to expand this knowledge and to explore the Csps contribution in other stress responses of this organism. In contrast to B. subtilis, in which at least one csp gene is essential for viability (14), none of the three csp genes is essential for L. monocytogenes viability. In fact, a mutant carrying deletions of all three csp genes could be generated without any discernable defects in the growth phenotype at 37°C, even under the defined minimal nutrient conditions of DM. It thus appears that functions encoded by the L. monocytogenes Csp genes are not critical requirements ...

MicroRNAs (miRNAs) are critical regulators responding to acute environmental stresses in both plants and animals. By modulating gene expression, miRNAs either restore or reconstitute a new expression program to enhance cell tolerance to stresses. Cold shock is one of the stresses that can induce acute physiological responses and transcriptional changes in aquatic creatures. Previous genomic studies have revealed many cold-affected genes in fish larvae and adults, however, the role of miRNAs in acute cold response is still ambiguous. To elucidate the regulatory roles of miRNAs in the cold-inducible responses, we performed small RNA-seq and RNA-seq analyses and found potential cold regulatory miRNAs and genes. We further investigated their interactions and involvements in cold tolerance. Small RNA-seq and RNA-seq identified 29 up-/26 down-regulated miRNAs and 908 up-/468 down-regulated genes, respectively, in responding to cold shock for 4 h at 18 °C. miRNA and transcriptomic analyses showed these miRNAs

The emergence and spread of antimicrobial resistance is the most urgent current threat to human and animal health. An improved understanding of the abundance of antimicrobial resistance genes and genes associated with microbial colonisation and pathogenicity in the animal gut will have a major role in reducing the contribution of animal production to this problem. Here, the influence of diet on the ruminal resistome and abundance of pathogenicity genes was assessed in ruminal digesta samples taken from 50 antibiotic-free beef cattle, comprising four cattle breeds receiving two diets containing different proportions of concentrate. Two hundred and four genes associated with antimicrobial resistance (AMR), colonisation, communication or pathogenicity functions were identified from 4966 metagenomic genes using KEGG identification. Both the diversity and abundance of these genes were higher in concentrate-fed animals. Chloramphenicol and microcin resistance genes were dominant in samples from forage-fed

Cyanobacterial and algal mass development, or blooms, have severe effects on freshwater and marine systems around the world. Many of these phototrophs produce a variety of potent toxins, contribute to oxygen depletion, and affect water quality in several ways. Coexisting antagonists, such as cyanolytic bacteria, hold the potential to suppress, or even terminate, such blooms, yet the nature of this interaction is not well studied. We isolated 31 cyanolytic bacteria affiliated with the genera Pseudomonas, Stenotrophomonas, Acinetobacter, and Delftia from three eutrophic freshwater lakes in Sweden and selected four phylogenetically diverse bacterial strains with strong-to-moderate lytic activity. To characterize their functional responses to the presence of cyanobacteria, we performed RNA sequencing (RNA-Seq) experiments on coculture incubations, with an initial predator-prey ratio of 1: 1.

After the first flush has happened do you need to do anything else like cold shock again or will more flushes just happen? How do you then distinguish between the flushes?
Chronic infections are often attributed to bacterial biofilms. These biofilms are extremely tolerant to antimicrobial treatment due to the presence of dormant persister cells. Whilst a number of persister genes and pathways have been identified, it is likely that others remain. Investigating persistence of S. Typhimurium was therefore undertaken. A csp null mutant of Salmonella enterica sv. Typhimurium, lacking all six cold shock protein (CspA) paralogues was previously constructed (Hutchinson 2005). At 10°C, this strain is unable to divide, but remains viable for several weeks. However it remains capable of growth at 37°C and thus is conditionally dormant. Using this strain, the link between dormancy and persistence was investigated. Treatment of stationary phase planktonic cultures with fluoroquinolones revealed persister cells in SL1344. In contrast the csp null mutant was completely eliminated by treatment at 37°C; this could be prevented by cspC or cspE expression, implicating a role for ...
