Available in PDF, EPUB and Kindle. Book excerpt: The ftsYEX operon of Escherichia coli historically has been described as a cluster of essential cell division genes. Filamentation temperature-sensitive (fts) designates a class of mutants that displays normal cell morphology at the permissive temperature of 30°C, but filaments and dies at the restrictive temperature of 42°C. The first gene, ftsY, is known to encode an essential component of a protein localization system first described in eukaryotes, the signal recognition particle (SRP) pathway. The function of the following genes, ftsE and ftsX, are much less understood. It has been shown that FtsE and FtsX comprise a two-component ATP-binding cassette (ABC) transporter, but the substrate is unknown. Constructing a null mutant of ftsE, I have demonstrated that ftsE is not an essential gene, although viability depends upon the concentration of NaCl or other compounds in the growth medium. In the characterization of this ftsE mutant, it was found that several predominant proteins were missing in this mutant when compared to wild-type protein profiles. Contrary to previous speculation, we have shown that the cell division septation machinery appears to be intact in an ftsE null mutant and it remains capable of forming septa. Regulation of the ftsYEX operon was investigated with the use of gene fusions. We have also constructed a plasmid shuffling system for the isolation of new mutants to further study the function of this operon. E. coli strains exhibiting a salt-dependent temperature-sensitive phenotype were also identified and investigated. This dissertation summarizes the scientific characterization of the ftsYEX operon of E. coli.

Download or read book ICRF Handbook of Genome Analysis written by N. S. Spurr and published by John Wiley & Sons. This book was released on 2009-06-03 with total page 1038 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combined power of genetic analysis and recombinant DNA technology to analyse entire genomes has moved biomedical research into a new and revolutionary phase. The complete sequencing and mapping of the human genome, as well as the genomes of other model organisms, will be the basis for our future understanding of human disease, and will allow us to answer fundamental questions about development and evolution. T The new ICRF Handbook of Genome Analysis is the essential guide to the enormous range of techniques available to the researcher for both the genetic and physical mapping of the genome, as well as the sequencing and analysis of DNA. It is both a protocol manual and a comprehensive information resource. Written by international experts, each chapter presents a state-of-the-art review of a methodology. Methods are fully described and evaluated; their advantages and disadvantages discussed; and their suitability for different investigations considered. Step-by-step protocols, including computer analyses, are given for 123 essential experimental procedures. 'Troubleshooting' sections discuss possible reasons for failure and offer remedies. The primary focus is on human genetics and the benefits of an understanding of the genome for the diagnosis and treatment of human disease. The book also considers the current state of progress in the analysis of genomes of many model organisms, including plants. A major part of the work provides detail on Internet resources as well as basic data on human and other genomes, including mapped disease genes and mouse knockouts. Covers not only the human genome in relation to cancers and other human diseases, but also the genomes of all important model organisms Contains 123 easy-to-follow protocols for essential experimental procedures Reviews a vast range of other information resources, including journals and the Internet * provides an invaluable listing of suppliers of laboratory materials Has been written by international experts from their own practical experience Is mandated by the Imperial Cancer Research Fund - a leader in research in this field Has a sturdy spiral binding within a hardback case for ease of use in the lab

This book was released on 2012-12-06 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emerging Targets in Antibacterial and Antifungal Chemotherapy offers constructive ideas to researchers that could lead to the discovery of entirely new classes of drugs. The authors emphasize new topics rather than review work on known antibacterials and antifungals, and identify new targets--either the rate-limiting component of a biochemical pathway or a component of the pathway that is susceptible to a ``screening'' or ``rational drug design'' approach. Each chapter reviews the biochemical pathway and its place in the cellular scheme in order to place the target in perspective. The authors, a mixture of academic researchers and drug-discovery investigators in pharmaceutical companies, also extend these theoretical concerns into practical applications and suggest useful screening methodologies. The importance of this subject area is demonstrated by the increasing number of papers in the literature that point to potential targets and screening methodologies for new antibacterials. This book also deals with antifungals, investigating the inherent limitations in existing antifungals (many of which are extremely toxic or have only limited efficacy), and pointing to major developments in the discovery of novel antifungals. Emerging Targets in Antibacterial and Antifungal Chemotherapy will be of interest to professional microbiologists, biochemists, and cell biologists in both academic and industrial laboratories.

Available in PDF, EPUB and Kindle. Book excerpt: Many individual aspects of the dynamics and assembly of biological membranes have been studied in great detail. Cell biological approaches, advanced genetics, biophysics and biochemistry have greatly contributed to an increase in our knowledge in this field.lt is obvious however, that the three major membrane constituents - lipids, proteins and carbohydrates- are studied, in most cases separately and that a coherent overview of the various aspects of membrane biogenesis is not readily available. The NATO Advanced Study Institute on "New Perspectives in the Dynamics of Assembly of Biomembranes" intended to provide such an overview: it was set up to teach students and specialists the achievements obtained in the various research areas and to try and integrate the numerous aspects of membrane assembly into a coherent framework. The articles in here reflect this. Statting with detailed contributions on phospholipid structure, dynamics, organization and biogenesis, an up to date overview of the basic, lipidic backbone of biomembranes is given. Extensive progress is made in the research on membrane protein biosynthesis. In particular the post- and co-translational modification processes of proteins, the mechanisms of protein translocation and the sorting mechanisms which are necessary to direct proteins to their final, intra - or extracellular destination have been characterized in detail. Modern genetic approaches were indispensable in this research area: gene cloning, hybrid protein construction, site directed mutagenesis and sequencing techniques elucidated many functional aspects of specific nucleic acid and amino acid sequences.

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.
