Lists of words, usually in alphabetical order, giving information about form, pronunciation, etymology, grammar, and meaning.
Bacteria
One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.
Biofilms
Encrustations, formed from microbes (bacteria, algae, fungi, plankton, or protozoa) embedding in extracellular polymers, that adhere to surfaces such as teeth (DENTAL DEPOSITS); PROSTHESES AND IMPLANTS; and catheters. Biofilms are prevented from forming by treating surfaces with DENTIFRICES; DISINFECTANTS; ANTI-INFECTIVE AGENTS; and antifouling agents.

Chromosome methylation and measurement of faithful, once and only once per cell cycle chromosome replication in Caulobacter crescentus. (1/444)

Caulobacter crescentus exhibits cell-type-specific control of chromosome replication and DNA methylation. Asymmetric cell division yields a replicating stalked cell and a nonreplicating swarmer cell. The motile swarmer cell must differentiate into a sessile stalked cell in order to replicate and execute asymmetric cell division. This program of cell division implies that chromosome replication initiates in the stalked cell only once per cell cycle. DNA methylation is restricted to the predivisional cell stage, and since DNA synthesis produces an unmethylated nascent strand, late DNA methylation also implies that DNA near the replication origin remains hemimethylated longer than DNA located further away. In this report, both assumptions are tested with an engineered Tn5-based transposon, Tn5Omega-MP. This allows a sensitive Southern blot assay that measures fully methylated, hemimethylated, and unmethylated DNA duplexes. Tn5Omega-MP was placed at 11 sites around the chromosome and it was clearly demonstrated that Tn5Omega-MP DNA near the replication origin remained hemimethylated longer than DNA located further away. One Tn5Omega-MP placed near the replication origin revealed small but detectable amounts of unmethylated duplex DNA in replicating stalked cells. Extra DNA synthesis produces a second unmethylated nascent strand. Therefore, measurement of unmethylated DNA is a critical test of the "once and only once per cell cycle" rule of chromosome replication in C. crescentus. Fewer than 1 in 1,000 stalked cells prematurely initiate a second round of chromosome replication. The implications for very precise negative control of chromosome replication are discussed with respect to the bacterial cell cycle.  (+info)

The CtrA response regulator mediates temporal control of gene expression during the Caulobacter cell cycle. (2/444)

In its role as a global response regulator, CtrA controls the transcription of a diverse group of genes at different times in the Caulobacter crescentus cell cycle. To understand the differential regulation of CtrA-controlled genes, we compared the expression of two of these genes, the fliQ flagellar gene and the ccrM DNA methyltransferase gene. Despite their similar promoter architecture, these genes are transcribed at different times in the cell cycle. PfliQ is activated earlier than PccrM. Phosphorylated CtrA (CtrA approximately P) bound to the CtrA recognition sequence in both promoters but had a 10- to 20-fold greater affinity for PfliQ. This difference in affinity correlates with temporal changes in the cellular levels of CtrA. Disrupting a unique inverted repeat element in PccrM significantly reduced promoter activity but not the timing of transcription initiation, suggesting that the inverted repeat does not play a major role in the temporal control of ccrM expression. Our data indicate that differences in the affinity of CtrA approximately P for PfliQ and PccrM regulate, in part, the temporal expression of these genes. However, the timing of fliQ transcription but not of ccrM transcription was altered in cells expressing a stable CtrA derivative, indicating that changes in CtrA approximately P levels alone cannot govern the cell cycle transcription of these genes. We propose that changes in the cellular concentration of CtrA approximately P and its interaction with accessory proteins influence the temporal expression of fliQ, ccrM, and other key cell cycle genes and ultimately the regulation of the cell cycle.  (+info)

Cell cycle-dependent polar localization of an essential bacterial histidine kinase that controls DNA replication and cell division. (3/444)

The master CtrA response regulator functions in Caulobacter to repress replication initiation in different phases of the cell cycle. Here, we identify an essential histidine kinase, CckA, that is responsible for CtrA activation by phosphorylation. Although CckA is present throughout the cell cycle, it moves to a cell pole in S phase, and upon cell division it disperses. Removal of the membrane-spanning region of CckA results in loss of polar localization and cell death. We propose that polar CckA functions to activate CtrA just after the initiation of DNA replication, thereby preventing premature reinitiations of chromosome replication. Thus, dynamic changes in cellular location of critical signal proteins provide a novel mechanism for the control of the prokaryote cell cycle.  (+info)

Identification and transcriptional control of the genes encoding the Caulobacter crescentus ClpXP protease. (4/444)

The region of the Caulobacter crescentus chromosome harboring the genes for the ClpXP protease was isolated and characterized. Comparison of the deduced amino acid sequences of the C. crescentus ClpP and ClpX proteins with those of their homologues from several gram-positive and gram-negative bacteria revealed stronger conservation for the ATPase regulatory subunit (ClpX) than for the peptidase subunit (ClpP). The C. crescentus clpX gene was shown by complementation analysis to be functional in Escherichia coli. However, clpX from E. coli was not able to substitute for the essential nature of the clpX gene in C. crescentus. The clpP and clpX genes are separated on the C. crescentus chromosome by an open reading frame pointing in the opposite direction from the clp genes, and transcription of clpP and clpX was found to be uncoupled. clpP is transcribed as a monocistronic unit with a promoter (PP1) located immediately upstream of the 5' end of the gene and a terminator structure following its 3' end. PP1 is under heat shock control and is induced upon entry of the cells into the stationary phase. At least three promoters for clpX (PX1, PX2, and PX3) were mapped in the clpP-clpX intergenic region. In contrast to PP1, the clpX promoters were found to be downregulated after heat shock but were also subject to growth phase control. In addition, the clpP and clpX promoters showed different activity patterns during the cell cycle. Together, these results demonstrate that the genes coding for the peptidase and the regulatory subunits of the ClpXP protease are under independent transcriptional control in C. crescentus. Determination of the numbers of ClpP and ClpX molecules per cell suggested that ClpX is the limiting component compared with ClpP.  (+info)

Cell cycle expression and transcriptional regulation of DNA topoisomerase IV genes in caulobacter. (5/444)

DNA replication and differentiation are closely coupled during the Caulobacter crescentus cell cycle. We have previously shown that DNA topoisomerase IV (topo IV), which is encoded by the parE and parC genes, is required for chromosomal partitioning, cell division, and differentiation in this bacterium (D. Ward and A. Newton, Mol. Microbiol. 26:897-910, 1997). We have examined the cell cycle regulation of parE and parC and report here that transcription of these topo IV genes is induced during the swarmer-to-stalked-cell transition when cells prepare for initiation of DNA synthesis. The regulation of parE and parC expression is not strictly coordinated, however. The rate of parE transcription increases ca. 20-fold during the G1-to-S-phase transition and in this respect, its pattern of regulation is similar to those of several other genes required for chromosome duplication. Transcription from the parC promoter, by contrast, is induced only two- to threefold during this cell cycle period. Steady-state ParE levels are also regulated, increasing ca. twofold from low levels in swarmer cells to a maximum immediately prior to cell division, while differences in ParC levels during the cell cycle could not be detected. These results suggest that topo IV activity may be regulated primarily through parE expression. The presumptive promoters of the topo IV genes display striking similarities to, as well as differences from, the consensus promoter recognized by the major Caulobacter sigma factor sigma73. We also present evidence that a conserved 8-mer sequence motif located in the spacers between the -10 and -35 elements of the parE and parC promoters is required for maximum levels of parE transcription, which raises the possibility that it may function as a positive regulatory element. The pattern of parE transcription and the parE and parC promoter architecture suggest that the topo IV genes belong to a specialized subset of cell cycle-regulated genes required for chromosome replication.  (+info)

Feedback control of a master bacterial cell-cycle regulator. (6/444)

The transcriptional regulator CtrA controls several key cell-cycle events in Caulobacter crescentus, including the initiation of DNA replication, DNA methylation, cell division, and flagellar biogenesis. CtrA is a member of the response regulator family of two component signal transduction systems. Caulobacter goes to great lengths to control the time and place of the activity of this critical regulatory factor during the cell cycle. These controls include temporally regulated transcription and phosphorylation and spatially restricted proteolysis. We report here that ctrA expression is under the control of two promoters: a promoter (P1) that is active only in the early predivisional cell and a stronger promoter (P2) that is active in the late predivisional cell. Both promoters exhibit CtrA-mediated feedback regulation: the early P1 promoter is negatively controlled by CtrA, and the late P2 promoter is under positive feedback control. The CtrA protein footprints conserved binding sites within the P1 and P2 promoters. We propose that the P1 promoter is activated after the initiation of DNA replication in the early predivisional cell. The ensuing accumulation of CtrA results in the activation of the P2 promoter and the repression of the P1 promoter late in the cell cycle. Thus, two transcriptional feedback loops coupled to cell cycle-regulated proteolysis and phosphorylation of the CtrA protein result in the pattern of CtrA activity required for the temporal and spatial control of multiple cell-cycle events.  (+info)

Regulation of podJ expression during the Caulobacter crescentus cell cycle. (7/444)

The polar organelle development gene, podJ, is expressed during the swarmer-to-stalked cell transition of the Caulobacter crescentus cell cycle. Mutants with insertions that inactivate the podJ gene are nonchemotactic, deficient in rosette formation, and resistant to polar bacteriophage, but they divide normally. In contrast, hyperexpression of podJ results in a lethal cell division defect. Nucleotide sequence analysis of the podJ promoter region revealed a binding site for the global response regulator, CtrA. Deletion of this site results in increased overall promoter activity, suggesting that CtrA is a negative regulator of the podJ promoter. Furthermore, synchronization studies have indicated that temporal regulation is not dependent on the presence of the CtrA binding site. Thus, although the level of podJ promoter activity is dependent on the CtrA binding site, the temporal control of podJ promoter expression is dependent on other factors.  (+info)

Bacterial cells: The migrating kinase and the master regulator. (8/444)

Dynamics and control of biofilms of the oligotrophic bacterium Caulobacter crescentus. | Alfred M. Spormann LaboratoryDynamics and control of biofilms of the oligotrophic bacterium Caulobacter crescentus. | Alfred M. Spormann Laboratory
Caulobacter crescentus is an oligotrophic alpha-proteobacterium with a complex cell cycle involving sessile-stalked and piliated, flagellated swarmer cells. Because the natural lifestyle of C. crescentus intrinsically involves a surface-associated, sessile state, we investigated the dynamics and control of C. crescentus biofilms developing on glass surfaces in a hydrodynamic system. In contrast to biofilms of the well-studied Pseudomonas aeruginosa, Escherichia coli, and Vibrio cholerae, C. crescentus CB15 cells form biphasic biofilms, consisting predominantly of a cell monolayer biofilm and a biofilm containing densely packed, mushroom-shaped structures. Based on comparisons between the C. crescentus strain CB15 wild type and its holdfast (hfsA; DeltaCC0095), pili (DeltapilA-cpaF::Omegaaac3), motility (motA), flagellum (flgH) mutants, and a double mutant lacking holdfast and flagellum (hfsA; flgH), a model for biofilm formation in C. crescentus is proposed. For both biofilm forms, the holdfast ...

This chapter focuses on the aquatic bacterium Caulobacter crescentus, which divides asymmetrically during each cell division cycle, yielding progeny cells that differ both structurally and functionally. The initially motile swarmer cell progeny sheds its flagellum and differentiates into a nonmotile stalked cell. In addition to morphological differences, the stalked- and swarmer cell progeny inherit different competencies for chromosome replication. A central component of any cell cycle is the initiation of chromosome replication coupled with strict controls to prevent repeated rounds of DNA replication without intervening cell divisions. The Caulobacter origin of replication was identified and cloned by taking advantage of the observation that replication is always initiated in the stalked cell. Microbial cells are able to monitor changes in their environment, detect changes in cell density, and communicate with each other and with other organisms through signals. The Caulobacter DnaA protein is a

Role of Transcription in the Temporal Control of Development in Caulobacter crescentus | PNASRole of Transcription in the Temporal Control of Development in Caulobacter crescentus | PNAS
The requirement for transcription during development of the stalked bacterium, Caulobacter crescentus, was studied with synchronous cultures of swarmer cells. The developmental pattern in these bacteria was first established by determination of the times at which specific changes in cell structure and function occurred. These changes could be divided into those characteristic of (a) development of the swarmer cell into the stalked cell: loss of motility and synthesis of the stalk, and (b) development of the stalked cell into the asymmetric dividing cell: chromosome replication, synthesis of the flagellum, motility, and division. The effect of rifampin in blocking several of these steps-loss of motility, initiation of chromosome replication, and cell division-indicates that RNA synthesis is required throughout the cell cycle for normal differentiation.. ...

The structural maintenance of chromosomes (SMC) complex plays an important role in chromosome organization and segregation in most living organisms. In Caulobacter crescentus, SMC is required to align the left and the right arms of the chromosome that run in parallel down the long axis of the cell. However, the mechanism of SMC-mediated alignment of chromosomal arms remains elusive. Here, using genome-wide methods and microscopy of single cells, we show that Caulobacter SMC is recruited to the centromeric parS site and that SMC-mediated arm alignment depends on the chromosome-partitioning protein ParB. We provide evidence that SMC likely tethers the parS-proximal regions of the chromosomal arms together, promoting arm alignment. Furthermore, we show that highly transcribed genes near parS that are oriented against SMC translocation disrupt arm alignment, suggesting that head-on transcription interferes with SMC translocation. Our results demonstrate a tight interdependence of bacterial chromosome

The biochemical properties of the maltodextrin-hydrolyzing enzymes of cold-tolerant proteobacterium Caulobacter crescentus CB15 remain to be elucidated, although whose maltodextrin transport systems were well investigated. We cloned the putative glucoamylase of C. crescentus CB15 (CauloGA) gene. The CauloGA gene product that was expressed in E. coli was prone to forming inclusion bodies; however, most of the gene product was expressed in a soluble and active form when it was expressed as a fusion protein with Staphylococcus Protein A. The fusion protein was purified using an IgG Sepharose column and was identified as the active GA. The optimum temperature and pH for the activity of this GA toward maltotriose as a substrate were approximately 40°C and 5.0, respectively, and a differential scanning fluorimetry (DSF) analysis revealed that the melting temperature (Tm) of CauloGA was 42.9°C. The kinetic analyses with maltotriose and other maltodextrins as the substrates indicated that CauloGA has higher

Deaths in the family cause bacteria to flee: IU News Room: Indiana UniversityDeaths in the family cause bacteria to flee: IU News Room: Indiana University
The deaths of nearby relatives have a curious effect on the bacterium Caulobacter crescentus -- surviving cells lose their stickiness. Indiana University Bloomington biologists report in an upcoming issue of Molecular Microbiology that exposure to the extracellular DNA (eDNA) released by dying neighbors stops the sticky holdfasts of living Caulobacter from adhering to surfaces, preventing cells from joining bacterial biofilms. Less sticky cells are more likely to escape established colonies, out to where conditions may be better.

Factors controlling in vitro recrystallization of the Caulobacter crescentus paracrystalline S-layer. | Journal of BacteriologyFactors controlling in vitro recrystallization of the Caulobacter crescentus paracrystalline S-layer. | Journal of Bacteriology
The S-layer of Caulobacter is a two-dimensional paracrystalline array on the cell surface composed of a single protein, RsaA. We have established conditions for preparation of stable, soluble protein and then efficient in vitro recrystallization of the purified protein. Efficient recrystallization and long range order could not be obtained with pure protein only, though it was apparent that calcium was required for crystallization. Recrystallization was obtained when lipid vesicles were provided, but only when the vesicles contained the specific species of Caulobacter smooth lipopolysaccharide (SLPS) that previous studies implicated as a requirement for attaching the S-layer to the cell surface. The specific type of phospholipids did not appear critical; phospholipids rather different from those present in Caulobacter membranes or archaebacterial tetraether lipids worked equally well. The source of LPS was critical; rough and smooth variants of Salmonella typhimurium LPS as well as the rough ...

Genome analysis identified a large number of genes that would enable utilization of dilute carbon sources and provides a comprehensive picture of the strategies used by C. crescentus for survival in nutrient-limiting conditions. Unlike E. coli and Vibrio cholerae, C. crescentus has no OmpF-type outer membrane porins that allow the passive diffusion of hydrophilic substrates across the outer membrane. However, it does possess 65 members of the family of TonB-dependent outer membrane channels that catalyze energy-dependent transport across the outer membrane. This is more than any other organism thus far characterized, with the next highest being 34 in Pseudomonas aeruginosa (32), and with no other sequenced proteobacteria possessing more than 10. C. crescentus has substantially fewer cytoplasmic membrane transporters relative to genome size than either E. coli or V. cholerae (33). Given C. crescentus low nutrient habitat, it is surprising that PTS or ATP-binding cassette domain transporters, ...

The holdfast is important for the attachment of C. crescentus cells to surfaces; however, little is known about the regulation of holdfast synthesis and holdfast attachment genes during the cell cycle. Furthermore, the time of holdfast appearance at the pole of the cell is not known. In this paper, we investigate two aspects of holdfast synthesis: the transcription of a holdfast attachment gene, hfaA, and the appearance of the holdfast at the pole of the cell. We demonstrate that hfaA transcription is temporally controlled during the cell cycle, with maximal transcription in the swarmer pole of the predivisional cell. We show that the holdfast is not present in swarmer cells or at the swarmer poles of predivisional cells. Our results suggest that the holdfast appears during the differentiation of swarmer to stalked cells.. The hfaA gene possesses a ς54 promoter sequence at the requisite distance from the transcription start site (16). However, our results indicate that hfaA is not transcribed ...

Caulobacter crescentus - WikipediaCaulobacter crescentus - Wikipedia
The Caulobacter cell cycle regulatory system controls many modular subsystems that organize the progression of cell growth and reproduction. A control system constructed using biochemical and genetic logic circuitry organizes the timing of initiation of each of these subsystems. The central feature of the cell cycle regulation is a cyclical genetic circuit-a cell cycle engine-that is centered around the successive interactions of five master regulatory proteins: DnaA, GcrA, CtrA, SciP, and CcrM whose roles were worked out by the laboratories of Lucy Shapiro and Harley McAdams.[8][9][10] These five proteins directly control the timing of expression of over 200 genes. The five master regulatory proteins are synthesized and then eliminated from the cell one after the other over the course of the cell cycle. Several additional cell signaling pathways are also essential to the proper functioning of this cell cycle engine. The principal role of these signaling pathways is to ensure reliable production ...

Distinct constrictive processes, separated in time and space, divide caulobacter inner and outer membranes | MetaDistinct constrictive processes, separated in time and space, divide caulobacter inner and outer membranes | Meta
Cryoelectron microscope tomography (cryoEM) and a fluorescence loss in photobleaching (FLIP) assay were used to characterize progression of the terminal stages of Caulobacter crescentus cell division. Tomographic cryoEM images of the cell division site show separate constrictive processes closing first the inner membrane (IM) and then the outer membrane (OM) in a manner distinctly different from that of septum-forming bacteria. FLIP experiments had previously shown cytoplasmic compartmentalization (when cytoplasmic proteins can no longer diffuse between the two nascent progeny cell compartments) occurring 18 min before daughter cell separation in a 135-min cell cycle so the two constrictive processes are separated in both time and space. In the very latest stages of both IM and OM constriction, short membrane tether structures are observed. The smallest observed pre-fission tethers were 60 nm in diameter for both the inner and outer membranes. Here, we also used FLIP experiments to show that ...

It is thought that S-layers protect cells from phages and large molecules. Using a combination of cellular electron cryo tomography (cryo-ET) with subtomogram averaging and X-ray crystallography we have determined the structure of the complete and intact S-layer lattice on Gram negative Caulobacter crescentus cells. We showed that the lattice formed in the crystals matches perfectly the lattice formed on cells as determined at 7.4 Å, directly on cells ...

IQSE Event AnnouncementIQSE Event Announcement
I will discuss our recent work that combined single-molecule imaging, fluorescence-recovery-after-photobleaching and optical tweezers to determine how the flagellar motor senses mechanical signals. I will present data that provides evidence that the chemotactic output of a molecular switch within the motor is influenced by the response to perturbations in viscous loads. The switch changes the direction of motorrotation and the torque generated is anisotropic. Yet, Caulobacter Crescentus cells that carry a single rigid flagellum, unlike E. coli cells that carry many, swim with similar speeds in the forward and backward directions. The resulting paradox that arises due to the time-reversibility of Stokes flow can be resolved with a simple model that incorporates cell-precession during swimming. Our observations indicate that motor mechanics are similar between the two species belonging to different classes of bacteria, and suggest that motor-mechanosensing might also be conserved. I will conclude ...

KEGG PATHWAY: Citrate cycle (TCA cycle) - Caulobacter crescentus NA1000KEGG PATHWAY: Citrate cycle (TCA cycle) - Caulobacter crescentus NA1000
The citrate cycle (TCA cycle, Krebs cycle) is an important aerobic pathway for the final steps of the oxidation of carbohydrates and fatty acids. The cycle starts with acetyl-CoA, the activated form of acetate, derived from glycolysis and pyruvate oxidation for carbohydrates and from beta oxidation of fatty acids. The two-carbon acetyl group in acetyl-CoA is transferred to the four-carbon compound of oxaloacetate to form the six-carbon compound of citrate. In a series of reactions two carbons in citrate are oxidized to CO2 and the reaction pathway supplies NADH for use in the oxidative phosphorylation and other metabolic processes. The pathway also supplies important precursor metabolites including 2-oxoglutarate. At the end of the cycle the remaining four-carbon part is transformed back to oxaloacetate. According to the genome sequence data, many organisms seem to lack genes for the full cycle [MD:M00009], but contain genes for specific segments [MD:M00010 M00011 ...

KEGG PATHWAY: Nucleotide excision repair - Caulobacter crescentus CB15KEGG PATHWAY: Nucleotide excision repair - Caulobacter crescentus CB15
Nucleotide excision repair (NER) is a mechanism to recognize and repair bulky DNA damage caused by compounds, environmental carcinogens, and exposure to UV-light. In humans hereditary defects in the NER pathway are linked to at least three diseases: xeroderma pigmentosum (XP), Cockayne syndrome (CS), and trichothiodystrophy (TTD). The repair of damaged DNA involves at least 30 polypeptides within two different sub-pathways of NER known as transcription-coupled repair (TCR-NER) and global genome repair (GGR-NER). TCR refers to the expedited repair of lesions located in the actively transcribed strand of genes by RNA polymerase II (RNAP II). In GGR-NER the first step of damage recognition involves XPC-hHR23B complex together with XPE complex (in prokaryotes, uvrAB complex). The following steps of GGR-NER and TCR-NER are similar ...

Second messenger-mediated spatiotemporal control of protein degradation regulates bacterial cell cycle progression - edocSecond messenger-mediated spatiotemporal control of protein degradation regulates bacterial cell cycle progression - edoc
Second messengers control a wide range of important cellular functions in eukaryotes and prokaryotes. Here we show that cyclic di-GMP, a global bacterial second messenger, promotes cell cycle progression in Caulobacter crescentus by mediating the specific degradation of the replication initiation inhibitor CtrA. During the G1-to-S-phase transition, both CtrA and its cognate protease ClpXP dynamically localize to the old cell pole, where CtrA is rapidly degraded. Sequestration of CtrA to the cell pole depends on PopA, a newly identified cyclic di-GMP effector protein. PopA itself localizes to the cell pole and directs CtrA to this subcellular site via the direct interaction with a mediator protein, RcdA. We present evidence that c-di-GMP regulates CtrA degradation during the cell cycle by controlling the dynamic sequestration of the PopA recruitment factor to the cell pole. Furthermore, we show that cell cycle timing of CtrA degradation relies on converging pathways responsible for substrate and ...

My research interests include Bacterial Cell Cycle Regulation and Signal Transduction mechanisms.. 1. Bacterial Cell Cycle Regulation- Epigenetic mechanisms regulating various physiological activities in the prokaryotic cells are increasingly being appreciated. Methylation of specific bases of the DNA molecule by methyltransferases is the most common epigenetic modification observed in the bacterial cells. This modification of nucleotides adds another level of regulation at the transcription; furthermore, it has a fundamental role in the cell physiological processes such as DNA replication, DNA mismatch repair, and virulence mechanisms in many pathogens. Among the prokaryotic DNA methyltransferases, Dam expressed among the Gammaproteobacteria is the most intensively studied. In contrast to Dam, another DNA methyltransferase CcrM (Cell Cycle Regulated Methylase) has been described in the Alphaproteobacteria, where it plays an important role in the cell cycle regulation of Caulobacter crescentus ...

Linking structural assembly to gene expression: a novel mechanism...: Ingenta ConnectLinking structural assembly to gene expression: a novel mechanism...: Ingenta Connect
In Caulobacter crescentus, the temporal and spatial expression of late flagellar genes is regulated by the 54 transcriptional activator, FlbD. Genetic experiments have indicated that the trans-acting factor FliX regulates FlbD in response to the progression of flagellar assembly, repressing FlbD activity until an early flagellar basal body structure is assembled. Following assembly of this structure, FliX is thought to function as an activator of FlbD. Here we have investigated the mechanism of FliX-mediated regulation of FlbD activity. In vitro transcription experiments showed that purified FliX could function as a repressor of FlbD-activated transcription. Transcription activated by a gain-of-function mutant of FlbD (FlbD-1204) that is active in vivo in the absence of an early flagellar structure, was resistant to the repressive effects of FliX. DNA binding studies showed that FliX inhibited the interaction of wild-type FlbD with enhancer DNA but did not effect FlbD-catalysed ATPase ...

ASMscience | Chromosomal Replication,ASMscience | Chromosomal Replication,
The study of chromosomal replication and cell division of bacteria has extended beyond Escherichia coli, and important insights have emerged recently from studies in other species, especially Bacillus subtilis and Caulobacter crescentus. Cell division is coordinated with other cell cycle events such as genomic DNA synthesis that leads to chromosomal replication and partition, increase of cell mass, and cell expansion by cell wall synthesis. This chapter reviews the information about predicted genes related to chromosomal replication, plasmid replication, and cell division in Helicobacter pylori, and a plausible replication machinery of the bacterium is discussed in light of the current understanding of bacterial organization and function of replication and cell division. The DnaA protein is essential for the initiation of chromosomal replication and is highly conserved among different bacteria. Clinical isolates of H. pylori have been reported to carry plasmids ranging in size from 1.5 to 40 kb. Three

ChIP-Chip E. coli - OpenWetWareChIP-Chip E. coli - OpenWetWare
ChIP-Chip stands for Chromatin Immunoprecipitation and chip in the sense of DNA microarray. It is a technique to determine the genome-wide binding sites of a DNA-binding protein. While the basic principle is the same for all species, there are some differences in handling cells. This protocol is developed and tested for E. coli. It should work the same way for other bacteria but that remains to be proven. Published protocols also exist for other bacterial species, including Bacillus subtilis, Caulobacter crescentus and Mycobacterium tuberculosis. Because E. coli can be grown to high cell densities relative to eukaryotes, it is possible to generate sufficient DNA to label without using a PCR-based method [1]. This method uses strand displacement primer extension with Klenow DNA polymerase and amplifies the DNA ~10-fold, while simultaneously incorporating dye-coupled nucleotide. Other ChIP-Chip protocols can be found here: ...

C. crescentus undergoes a developmental step during its division cycle from a motile cell unable to replicate its DNA to a nonmotile cell that is competent for chromosome replication. We use synchronized populations of motile G1-phase cells to study the events that occur during development. C. crescentus also divides asymmetrically, producing one motile and one nonmotile cell at each division. Proteins in the predivisional cell are segregated to opposite ends to mediate the differentiation of identity after division. We study the locations and movements of individual proteins using fluorescence microscopy.. Specific problems that we are investigating include the following: regulated degradation of a key transcription factor during the motile-sessile developmental step; the roles, locations, and interactions of enzymes that participate in cell wall biosynthesis; and the regulatory functions of protein phosphorylation on serine, threonine, or tyrosine residues. ...

Nanotechnology Now - Press Release: How Do Bacteria Swim? Brown Physicists ExplainNanotechnology Now - Press Release: How Do Bacteria Swim? Brown Physicists Explain
Caulobacter is a single-celled organism with a filament-like tail called a flagellum. As it swims, its rounded cellular head rotates in one direction, while the tail rotates in the opposite direction. This creates torque, which helps explain the bacteriums nonlinear movement through a fluid. What Tang and his team found, however, is that Caulobacter also is influenced by Brownian motion, which is the zigzagging motion that occurs when immersed particles are buffeted by the actions of the molecules of the surrounding medium. What that means, in effect, is that Caulobacter is being pinballed by the water molecules surrounding it as it swims ...

Generation and filtering of gene expression noise by the bacterial cell cycle | BMC Biology | Full TextGeneration and filtering of gene expression noise by the bacterial cell cycle | BMC Biology | Full Text
Gene expression within cells is known to fluctuate stochastically in time. However, the origins of gene expression noise remain incompletely understood. The bacterial cell cycle has been suggested as one source, involving chromosome replication, exponential volume growth, and various other changes in cellular composition. Elucidating how these factors give rise to expression variations is important to models of cellular homeostasis, fidelity of signal transmission, and cell-fate decisions. Using single-cell time-lapse microscopy, we measured cellular growth as well as fluctuations in the expression rate of a fluorescent protein and its concentration. We found that, within the population, the mean expression rate doubles throughout the cell cycle with a characteristic cell cycle phase dependent shape which is different for slow and fast growth rates. At low growth rate, we find the mean expression rate was initially flat, and then rose approximately linearly by a factor two until the end of the cell

Bacterial Cytoskeleton May Offer New Drug TargetBacterial Cytoskeleton May Offer New Drug Target
In fact, it was only in the late 1990s that biologists discovered bacteria even had a cytoskeleton. The cytoskeleton was first identified in the cells of eukaryotic organisms (those, such as plants and animals, whose cells have specialized organelles and a discrete nucleus). Bacteria are tiny, for one thing, and until the advent of advanced imaging technology, scientists could not get a good look inside. The species Goley studies, Caulobacter crescentus, is a mere 500 nanometers across, or about one one-hundredth the size of an average human cell.. Second, a cell wall encases most bacterial species, and scientists assumed this semi-rigid structure obviated the need for a cytoskeleton.. These assumptions turned out to be wrong. In 1998, structural biologist Jan Löwe, in the United Kingdom, demonstrated that a bacterial protein called FtsZ is an evolutionary counterpart of tubulin, a key protein component of the eukaryote cytoskeleton. The finding implied that the cytoskeleton was not a ...

Mutual regulation causes co-entrainment between a synthetic oscillator and the bacterial cell cycleMutual regulation causes co-entrainment between a synthetic oscillator and the bacterial cell cycle
The correct functioning of cells requires the orchestration of multiple cellular processes, many of which are inherently dynamical. The conditions under which these dynamical processes entrain each other remain unclear. Here we use synthetic biology to address this question in the case of concurrent cellular oscillations. Specifically, we study at the single-cell level the interaction between the cell division cycle and a robust synthetic gene oscillator in Escherichia coli. Our results suggest that cell division is able to partially entrain the synthetic oscillations under normal growth conditions, by driving the periodic replication of the genes involved in the oscillator. Coupling the synthetic oscillations back into the cell cycle via the expression of a key regulator of chromosome replication increases the synchronization between the two periodic processes. A simple computational model allows us to confirm this effect ...

City of Hope, Duarte, CA, USA. Abstract: Background/Purpose Genetic/genomic cancer risk assessment (GCRA) identifies and prescribes personalized screening and prevention care for individuals and families with increased cancer risk, often prior to disease onset, when early detection or prevention strategies are most effective. GCRA is standard of care in most developed countries, but is not available in most of Latin America. Documented barriers include lack of affordable genomic tools, limited knowledge about GCRA among key stakeholders, and absence of clinicians trained for GCRA. City of Hope is leveraging the robust training resources of its Clinical Cancer Genetics Community of Practice (CCGCoP) to address the need for GCRA education and training in Latin America. Description The CCGCoP is a flexible, multi-modal program of distance didactics, face-to-face case-based workshops and continuing practice support. A program priority is training clinicians in underserved areas across the U.S. and ...

  • [3] In the Lewis lung carcinoma model, 60% of the mice pre-immunized with live C. crescentus were still alive by day 90, whereas all mice pre-immunized with heat killed C. crescentus or the saline control died by 8 weeks post tumor challenge. (kenyon.edu)
  • [3] In the murine L1210 leukemia model, the entire control group only survived until the fourth week, whereas approximately 80% of mice pre-immunized with live C. crescentus survived, and 100% of the heat-killed immunized mice survived the entire 3-month study period. (kenyon.edu)
  • flgH), a model for biofilm formation in C. crescentus is proposed. (stanford.edu)
Glucose2
  • Glucose, the only carbon source in the minimal media M2G was removed from C. crescentus exponential phase cultures, and total RNA was extracted after 30 and 60 minutes of incubation. (omicsdi.org)
  • CrfA was found to be upregulated 10-fold in C. crescentus when glucose was deprived in a minimal medium. (wikipedia.org)
