DNA methylation, a modification found in most species, regulates chromatin functions in conjunction with other epigenome modifications, such as histone post-translational modifications and non-coding RNAs. In mammals, DNA methylation has an essential role in development by orchestrating the generation and maintenance of the phenotypic diversity of human cell types. Recent years have brought spectacular advances in our understanding of the mechanism, function and regulation of DNA methyltransferases through their interaction with other epigenome modifications, chromatin factors and post-translational modifications, which are described in this Special Issue of Genes. Manuscripts are specifically addressing describing the targeting and regulation of DNA methyltransferases by interacting factors and their roles in cellular differentiation and the development of diseases.

Annotation The development of new enzymes is one of the most thriving branches of biotechnology. Although the applications of enzymes are already well established in some areas, recent advances in modern biotechnology have revolutionized the development of new enzymes. The use of genetic engineering has further improved manufacturing processes and enabled the commercialization of enzymes that could previously not be produced. Protein engineering and the possibility of introducing small changes to proteins are bringing ever more powerful means of analysis to the study of enzyme structure and its biochemical and biophysical properties, which have leading to the rational modification of enzymes to match specific requirements and also the design of new enzymes with novel properties. The developments in bioinformatics and the availability of sequence data have significantly increased the efficiency of identifying genes with biotech potential from nature. Complementary to chemical synthesis, biosynthesis of drug metabolites with mammalian or microbial bioreactors offers certain advantages, and sometime is the only practical route to the desired metabolite. At the same time, new technological developments are stimulating the chemical and pharmaceutical industry to embrace enzyme technology. Altogether, these advances have made it possible to provide tailor-made enzymes displaying new activities and adapted to new process conditions, enabling a further expansion of their use in several branches of biotechnology. This Special Issue focuses on the discovery and development of new enzymes and their applications in different areas of biotechnology. The Special Issue contains a collection of papers written by authors who are leading experts in the field including selected papers from the 4th International Symposium on Enzymes & Biocatalysis (SEB-2013).

This book gives a current review of the links between the structure and function of hydrolases and ligases, as well as ideas for better using these critical enzymes. The book is split into two sections: "Cleavage" and "Ligases." These enzymes are the biggest and most varied family of enzymes, allowing researchers to investigate the structural variety that underpins their different biological roles. In light of recent scientific advances, there is a desire to examine and update our knowledge of these enzymes' functional and structural changes.

"This book will cover all aspects of using nanozymes for environmental safety, monitoring and remediation. It will uncover the way nanozymes are being used for sensing different categories of environmental pollutants like pesticides, heavy metals, organic pollutants or microbes. Further, it will provide information on using nanozymes for extraction, removal or remediation of pollutants from soil or water samples and their degradation to relatively safer by-products. This book will also include the challenges to be met by nanozymes and their future prospects"--

Enzyme immobilization has been approached for finding solutions for various critical problems associated with industries, medicine, environment, agriculture, etc. Especially since last decades, several innovative researches have come up to look for enhancing catalytic efficiency, reusability of immobilized enzyme and longer stability by introducing range of immobilizing supports, supports modifiers through introduction of several chemical agents (non-toxic) and adopting innovative enzyme immobilization methods. In the present book, polymeric supports have been focussed for enzyme immobilization, especially due to their versatility in immobilizing different enzymes for different large scale enzyme reactors to be used for several applications. Especially, polymers can be modified according to applications and enzyme properties which have made it supports of choice for all several enzyme based applications. Polymeric Supports for Enzyme Immobilization: Opportunities and Applications offers in-depth discussions of known polymeric enzyme support materials, reaction processes, and optimized methods to enhance enzyme immobilization. Case-based chapters examine methods of enzyme immobilization onto various polymeric supports, their surface chemistry and physical morphology followed by implementation of polymers based immobilized enzymes in various applications, viz. medicine, environment, industries, clean energy, disease diagnosis, drug delivery etc. This book has prime focus to allow several researchers across the world to provide updated technological details and incite to contribute more innovative work in coming years to find solutions to several critical problems.
