The first of its kind, this volume presents the latest research findings on the chaperonins, the best studied family of a class of proteins known as molecular chaperones. These findings are changing our view of some fundamental cellular processes involving proteins, especially how proteins fold into their functional conformations. - Origins of the new view of protein folding - Prokaryotic chaperonins - Eukaryotic chaperonins - Evolution of the chaperonins - Refolding of denatured proteins - Organelle biosynthesis - Biomedical aspects
This book describes antibiotic resistance amongst pathogenic bacteria. It starts with an overview of the erosion of the efficacy of antibiotics by resistance and the decrease in the rate of replacement of redundant compounds. The origins of antibiotic resistance are then described. It is proposed that there is a large bacterial resistome which is a collection of all resistance genes and their precursors in both pathogenic and non-pathogenic bacteria. Ongoing resistance surveillance programs are also discussed, together with the perspective of a clinical microbiologist. The book then turns to specific themes such as the most serious area of resistance in pathogens, namely in Gram-negative org...
Contains abstracts of papers presented at meeting of the Society for General Microbiology.
Bacterial toxins that act inside cells interact very specifically with key components of the cell and some even manipulate the cell in subtle ways for their own purposes. These potent toxins, described in this 2005 book, will be of interest to both microbiologists and cell biologists. Some of these toxins are conventional multidomain toxins that are self-programmed to enter cells. Others are delivered by type III mechanisms, often as a package of potent molecules. The molecular targets for all these toxins mediate signal transduction and the cell cycle to regulate the crucial processes of cell growth, cell division and differentiation. Thus these potent toxins are not only responsible for disease, but also provide a powerful set of tools with which to interrogate the biology of the cell. In addition such toxins may act directly to promote carcinogenesis and hence their study is also of interest in a wider context.
