This volume is a timely and comprehensive description of the many facets of DNA and RNA modification-editing processes and to some extent repair mechanisms. Each chapter offers fundamental principles as well as up to date information on recent advances in the field (up to end 2008) They ended by a short ‘conclusion and future prospect’ section and an exhaustive list of 35 to up to 257 references (in average 87) Contributors are geneticists, structural enzymologists and molecular biologists working at the forefront of this exciting, fast-moving and diverse field of researches. This book will be a major interest to PhD students and University teachers alike. It will also serve as an invaluable reference tool for new researchers in the field, as well as for specialists of RNA modification enzymes generally not well informed about what is going on in similar processes acting on DNA and vice-versa for specialists of the DNA modification-editing and repair processes usually not much acquainted with what is going on in the RNA maturation field. The book is subdivided into 41 chapters (740 pages) The common links between them are mainly the enzymatic aspects of the different modification-editing and repair machineries: structural, mechanistic, functional and evolutionary aspects. It starts with two general and historical overview of the discovery of modified nucleosides in DNA and RNA and corresponding modification-editing enzymes. Then follows eleven chapters on DNA modification and editing (mechanistic and functional aspects) Two additional chapters cover problems related to DNA/RNA repair and base editing by C-to-U deaminases, followed by three chapters on RNA editing by C-to-U and A-to-I type of deamination. Discussions about interplay between DNA and RNA modifications and the emergence of DNA are covered in two independent chapters, followed by twenty chapters on different but complementary aspects of RNA modification enzymes and their cellular implications. The last chapter concerns the description of the present state-of-the art for incorporating modified nucleosides by in vitro chemical synthesis. At the end of the book, six appendicies give useful details on modified nucleosides, modification-editing enzymes and nucleosides analogs. This information is usually difficult to obtain from current scientific literature.

RNA Modification, Volume 41 examines the powerful ability to regulate the function of RNA molecules or modify the message transmitted by RNA molecules. Chapters in this newly released volume include The Importance of Being Modified: Modifications Shape RNA Function through Chemistry, Structure and Dynamics, The evolution of multi-substrate specificity by RNA modification enzymes, TrmD: a methyl transferase for tRNA methylation with m1G37, Structures and activities of the Elongator complex and its co-factors, RNA pseudouridylation: Mechanism and Function, The activity of 5’3' exonucleases on hypo modified tRNA substrates and other structured RNAs, and the Synthesis, heterogeneity and function of post-transcriptional nucleotide modifications in eukaryotic ribosomal RNAs. This field has recently seen a very rapid progress in the understanding of the mechanism and enzymes involved in RNA modification. This volume presents some of the most recent advances in the identification and function of enzymes involved in modifying RNA molecules. Features authoritative expertise from recognized contributors to the field Presents the most recent advances in the rapidly evolving field of RNA modification Covers the identification and function of enzymes involved in modifying RNA molecules

The First volume gives an overview of the enzymes involved in DNA synthesis and modification; the second volume deals with the RNA-enzymes. Although the major emphasis of the book is on eukaryotic enzymes, a separate chapter dealing with prokaryotic DNA repair enzymes has been included to discuss the major advances in this field in recent years. There are two separate chapters on RNA polymerases to provide a comprehensive coverage of the enzymes from lower eukaryotes, plants and higher eukaryotes.

Naturally occurring RNA always contains numerous biochemically altered nucleotides. They are formed by enzymatic modification of the primary transcripts during the complex RNA maturation process designated RNA modification. A large number of enzymes catalyzing the formation of these modified nucleosides or converting one canonical base into another at the posttranscriptional level have been studied for many years, but only recently have systematic and comparative studies begun. The functions of individual enzymes and/or the modified/edited nucleosides in RNA, however, have remained largely ignored. This book provides advance information on RNA modification, including the associated editing machinery, while offering the reader some perspective on the significance of such modifications in fine-tuning the structure and functions of mature RNA molecules and hence the ability to influence the efficiency and accuracy of genetic expression. Outstanding scientists who are actively working on RNA modification/editing processes have provided up-to-date information on these intriguing cellular processes that have been generated over the course of millions of years in all living organisms. Each review has been written and illustrated for a large audience of readers, not only specialists in the field, but also for advanced students or researchers who want to learn more about recent progress in RNA modification and editing.
