Post-translational modifications (PTMs) are widely employed by all living organisms to control the enzymatic activity, localization or stability of proteins on a much shorter time scale than the transcriptional control. In eukarya, global analyses consistently reveal that proteins are very extensively phosphorylated, acetylated and ubiquitylated. Glycosylation and methylation are also very common, and myriad other PTMs, most with a proven regulatory potential, are being discovered continuously. The emergent picture is that PTM sites on a single protein are not independent; modification of one residue often affects (positively or negatively) modification of other sites on the same protein. The best example of this complex behavior is the histone “bar-code” with very extensive cross-talk between phosphorylation, acetylation and methylation sites. Traditionally it was believed that large networks of PTMs exist only in complex eukaryal cells, which exploit them for coordination and fine-tuning of various cellular functions. PTMs have also been detected in bacteria, but the early examples focused on a few important regulatory events, based mainly on protein phosphorylation. The global importance (and abundance) of PTMs in bacterial physiology was systematically underestimated. In recent years, global studies have reported large datasets of phosphorylated, acetylated and glycosylated proteins in bacteria. Other modifications of bacterial proteins have been recently described: pupylation, methylation, sirtuin acetylation, lipidation, carboxylation and bacillithiolation. As the landscape of PTMs in bacterial cells is rapidly expanding, primarily due to advances of detection methods in mass spectrometry, our research field is adapting to comprehend the potential impact of these modifications on the cellular physiology. The field of protein phosphorylation, especially of the Ser/Thr/Tyr type, has been profoundly transformed. We have become aware that bacterial kinases phosphorylate many protein substrates and thus constitute regulatory nodes with potential for signal integration. They also engage in cross-talk and eukaryal-like mutual activation cascades. The regulatory potential of protein acetylation and glycosylation in bacteria is also rapidly emerging, and the cross-talk between acetylation and phosphorylation has been documented. This topic deals with the complexity of the PTM landscape in bacteria, and focus in particular on the physiological roles that PTMs play and methods to study them. The topic is associated to the 1st International Conference on Post-Translational Modifications in Bacteria (September 9-10, 2014, Göttingen, Germany).

The remarkable ability to target one or even a couple of sites on a large protein with a small molecule, under photochemical control, is a considerable challenge and this challenge has been addressed in some depth in this book. Systematic modification of the structure of the photoreagent provided valuable information on the binding site recognition as well as the mechanism of the photocleavage reaction. Some factors that impact the photocleavage reaction include the exact location of the probe binding site on the protein, conformations of the bound probe at the binding site, protein size, functional groups present on the probe that interact with the protein surroundings either in a favorable or unfavorable manner, overall charge on the photoreagent, and photophysical as well as photochemical properties of the probe. The protein photocleavage studies, in all case, were preceded by detailed binding studies by a variety of spectroscopic methods. Methods as simple as absorption and fluorescence spectroscopies or more sophisticated circular dichroism spectroscopy were used. Conclusions that are most consistent with the binding data indicated a single binding site on most proteins, irrespective of the probe or the protein, with only one exception noted so far. Photoactivation of the bound probe resulted in protein cleavage at a single site, in many instances. The specificity for the reaction has been investigated in detail and molecular modeling studies provided a firm ground to rationalize the observed cleavage sites. The reagents provide unique tools for sequencing large proteins by converting them into smaller fragments by non-biochemical transformations. Understanding of the rules for the above methodology are also investigated which provided rational methods for the design of small molecules that could bind at particular sites on large proteins, and this is a major breakthrough for a variety of fields including drug design, protein targeting, mass spectrometry, proteomics and other cutting-edge research areas.

The new edition of Gene Control, for the first time, provides extensive coverage on prokaryotic gene regulation, which makes it the only textbook offering a complete and detailed account of gene control for both prokaryotic and eukaryotic organisms. The core objective of this edition is to educate students about the fundamental principles and mechanisms governing gene expression, regulation, and function. To reinforce these ideas, each chapter now includes discussion questions to promote critical thinking. There are also multiple choice questions and animations for students, and a large question bank and figure slides for instructors. The textbook also emphasizes the vital role of scientific experiments and evidence in shaping our current understanding of gene control and provides comprehensive coverage of essential gene expression techniques and methodologies throughout the book. This extensively updated edition of the renowned textbook Gene Control will remain a valuable resource for students, instructors, researchers, and medical professionals exploring various aspects of gene control, ranging from the regulation of genes in infectious diseases to embryonic development across different organisms, from bacteria to humans.

In the past few years there has been the increased recognition that the effects of oxidative stress are not limited to the damage of cellular constituents. There is now evidence that reactive oxygen species (ROS) can alter cell function by acting upon the intermediates, or second messengers, in signal transductions. Such effects on signaling mechanisms probably account for the role of oxidative stress in inflammation, aging, and cancer. This volume brings together internationally recognized researchers in both the major areas covered by the book, oxidative stress and signal transduction. The work is organized in three sections. The first deals with the immediate cellular responses to oxidative stress and the production of second messengers. The second details the connection between second messengers and the gene. The third part looks more closely at the level of the gene.

The Overview of the Topic was the following: "One of the most active areas of research in molecular microbiology has been the study of how bacteria modulate their genetic activity and its consequences. The prokaryotic world has gained a lot of interest. In addition to the above, the invention is based on the subject-matter of the present invention, which is incorporated herein by reference in its entirety. All of these processes are fundamental to the operation of a genetic entity and condition their lifestyle. Further, the discoveries in the bacterial world have been of ample use in eukaryotes. [Article in German] Hansen, Hansen, H. (2003). In addition to the fundamental interest in understanding modulation of prokaryotic lifestyle by DNA binding proteins, As it is well-known the antibiotic-resistance strains of pathogenic bacteria are a major world problem, so that there is an urgent need of innovative technologies to tackle it. Most of the patients are infected with the virus. It is an imperative of finding new alternatives to the 'classical' way of treatment of bacterial infections and these new alternatives. Nevertheless, These new alternatives will find a dead-end if we are unable to obtain a better understanding of the basic processes modulating bacterial gene expression. Our goal is to achieve our understanding of protein-DNA interactions. First, the topic will bring together a lot of very active research in the study of gene replication, gene regulation, the strategies. We therefore want to acquire an in-depth knowledge of some of the mechanisms of gene regulation, gene transfer, and gene replication. Further, the readers of the papers will realize the importance of the topic and will learn the most recent thinking, results, and approaches in the area ". We are fully confident that we have exceeded our expectations. Now we are proud to present the final output of the topic, which is the eBook. It includes 24 articles contributed by 118 authors. As of today, March, 16th, January 2017, the total number of readings has reached 19,284, 14,921 article views, and 2,944 article downloads.
