Download or read book Stress and Environmental Regulation of Gene Expression and Adaptation in Bacteria written by Frans J. de Bruijn and published by John Wiley & Sons. This book was released on 2016-07-13 with total page 1472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacteria in various habitats are subject to continuously changing environmental conditions, such as nutrient deprivation, heat and cold stress, UV radiation, oxidative stress, dessication, acid stress, nitrosative stress, cell envelope stress, heavy metal exposure, osmotic stress, and others. In order to survive, they have to respond to these conditions by adapting their physiology through sometimes drastic changes in gene expression. In addition they may adapt by changing their morphology, forming biofilms, fruiting bodies or spores, filaments, Viable But Not Culturable (VBNC) cells or moving away from stress compounds via chemotaxis. Changes in gene expression constitute the main component of the bacterial response to stress and environmental changes, and involve a myriad of different mechanisms, including (alternative) sigma factors, bi- or tri-component regulatory systems, small non-coding RNA’s, chaperones, CHRIS-Cas systems, DNA repair, toxin-antitoxin systems, the stringent response, efflux pumps, alarmones, and modulation of the cell envelope or membranes, to name a few. Many regulatory elements are conserved in different bacteria; however there are endless variations on the theme and novel elements of gene regulation in bacteria inhabiting particular environments are constantly being discovered. Especially in (pathogenic) bacteria colonizing the human body a plethora of bacterial responses to innate stresses such as pH, reactive nitrogen and oxygen species and antibiotic stress are being described. An attempt is made to not only cover model systems but give a broad overview of the stress-responsive regulatory systems in a variety of bacteria, including medically important bacteria, where elucidation of certain aspects of these systems could lead to treatment strategies of the pathogens. Many of the regulatory systems being uncovered are specific, but there is also considerable “cross-talk” between different circuits. Stress and Environmental Regulation of Gene Expression and Adaptation in Bacteria is a comprehensive two-volume work bringing together both review and original research articles on key topics in stress and environmental control of gene expression in bacteria. Volume One contains key overview chapters, as well as content on one/two/three component regulatory systems and stress responses, sigma factors and stress responses, small non-coding RNAs and stress responses, toxin-antitoxin systems and stress responses, stringent response to stress, responses to UV irradiation, SOS and double stranded systems repair systems and stress, adaptation to both oxidative and osmotic stress, and desiccation tolerance and drought stress. Volume Two covers heat shock responses, chaperonins and stress, cold shock responses, adaptation to acid stress, nitrosative stress, and envelope stress, as well as iron homeostasis, metal resistance, quorum sensing, chemotaxis and biofilm formation, and viable but not culturable (VBNC) cells. Covering the full breadth of current stress and environmental control of gene expression studies and expanding it towards future advances in the field, these two volumes are a one-stop reference for (non) medical molecular geneticists interested in gene regulation under stress.

Available in PDF, EPUB and Kindle. Book excerpt: The reductionist approach of molecular biology has given us detailed descriptions for many biochemical constituents of complex biological systems. For some of the simpler systems nearly the entire "parts catalog" has been assembled. These developments have set the stage for a new generation of questions -- questions of integration that deal with the relation between behavior of intact systems and their underlying molecular determinants, questions of unifying design principles that will give meaning to the bewildering diversity of alternative molecular designs, questions of higher-level theory and quantitative prediction, which currently are not available in most of biology. The motivation to develop this new perspective comes from the study of complex biochemical pathways, intricate circuits of gene regulation, network interactions within the immune system, plasticity of neural networks, and pattern formation by cellular networks. All these networks consist of more elemental constituents that find their meaning within the context of the intact system. The integrative perspective requires a new language and methodology. The objective of this text is to systematically develop these and to apply them to specific classes of metabolic networks and gene circuitry. The applications demonstrate the power of this approach to formulate and answer fundamental questions concerning network function, design and evolution that currently cannot be addressed by other methods. The text was first published in 1976 and is being reissued to commemorate the 40th anniversary of the author's first paper published on Biochemical Systems Analysis.

Download or read book Lactic Acid Bacteria Genetics Metabolism and Applications written by Roland J. Siezen and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foods fermented with lactic acid bacteria are an important part of the human diet. Lactic acid bacteria play an essential role in the preservation of food raw materials and contribute to the nutritional, organoleptic, and health properties of food products and animal feed. The importance of lactic acid bacteria in the production of foods throughout the world has resulted in a continued scientific interest in these micro-organisms over the last two decades by academic research groups as well as by industry. This research has resulted in a number of important scientific breakthroughs and has led to new applications. The most recent of these advances is the establishment of the complete genome sequences of a number of different lactic acid bacterial species. To communicate and stimulate the research on lactic acid bacteria and their applications, a series of tri-annual symposia on lactic acid bacteria was started in 1983 under the auspices of the Netherlands Society for Microbiology (NVVM), which was later also supported by the Federation of European Microbiological Societies (FEMS). The aim of these state-of-the-art symposia is to offer a unique platform for universities, institutes, and industry in this area of biotechnology, to present recent work, to obtain information on new developments, and to exchange views with colleagues from all over the world on scientific progress and applications. The growing number of participants at these symposia has been a clear demonstration of the interest of the international industrial and scientific community in this area of research. The 7th Symposium is based on a number of plenary lectures that review the scientific progress of the last years in the different areas of research on lactic acid bacteria, and which are documented in this special issue of Antonie van Leeuwenhoek.
Download or read book Transcriptional Regulation and Autogenous Control of the Genes for the and Subunits of Escherichia Coli RNA Polymerase microform written by Steward, Keith L., 1962 and published by National Library of Canada = Bibliothèque nationale du Canada. This book was released on 1994 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transcriptional control of the two genes rpoB and rpoC encoding the $\beta$ and $\beta\sp\prime$ subunits of RNA polymerase was examined in a systematic fashion in order to evaluate the contribution of such control to the autogenous regulation of RNA polymerase synthesis. Numerous transcriptional fusions were constructed by placing restriction fragments of the rplKaJLrpoBC gene cluster upstream of the lacZ reporter gene on $\lambda$ phage vectors. Assaying $\beta$-galactosidase activity from monolysogens of the recombinant phage permitted a high resolution scan of the gene cluster for transcriptional controls. The results precisely quantitate the efficiencies of two strong promoters, rplKp and rplJp, a weak promoter rplLp, and a transcriptional attenuator rpoBa located between rplL and rpoB. From this data, the relative contribution of each transcriptional signal to the overall transcription of rpoBC was determined. It was found that almost all transcription initiated from the strong rplKp promoter continued into the downstream rplJLrpoB genes; that rplJp continues to initiate efficiently despite such transcription from the upstream promoter; and most surprisingly, that the efficiency of termination at the rpoBa attenuator depended on whether transcription was initiated from rplKp, rplJp, or both promoters. Further examination of the latter phenomenon revealed that the efficiency of rpoBa was related in an inverse fashion to the frequency of transcription initiated by promoters located upstream of it. When the frequency of transcription into the attenuator was decreased over a 40-fold range by replacing rplJp and rplKp with alternative promoters, readthrough at rpoBa increased from 19% to 61%. When regions located upstream of rpoBa are deleted or inverted, the modulation of rpoBa may be abrogated. In addition, sequence analysis of the region can identify a site with remarkable homology to the boxB motif of the $\lambda\ nutR$ site. Such findings suggest the potential involvement of antitermination in the modulation of rpoBa function. Modulation of rpoBa, together with the evidence by others that the global frequency of transcription is influenced by the cellular concentration of RNA polymerase, suggests that rpoBa may play a role in the autogenous control of rpoBC expression.
Download or read book Corynebacterium glutamicum written by Nami Tatsumi and published by Springer Science & Business Media. This book was released on 2012-08-14 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corynebacterium glutamicum was discovered in Japan in 1956 as a natural glutamate producer. Its “microbial factory” qualities, such as its physiological plasticity and robust catalytic functionalities, have since facilitated the development of efficient production processes for amino acids, nucleotides and vitamins. This monograph illustrates how the information gleaned from complete genome sequencing allows the rational engineering of the entire cellular metabolism and how systems biology permits the further optimization of C. glutamicum as a biocatalyst. Aspects of gene regulation, metabolic pathways, sugar uptake, protein secretion, cell division and biorefinery applications highlight the enormous biotechnological and biorefinery potential.
