The discovery that RNA could act as a macromolecular catalyst in the cell, signified a paradigm shift in molecular biology. Ribozymes and RNA Catalysis takes the reader through the origins of catalysis in RNA and necessarily includes significant discussion of structure and folding. The main focus of the book concerns chemical mechanism with extensive comment on how, despite the importance of RNA catalysis in the cell, its origins are still poorly understood and often controversial. The reader is given an outline of the important role of RNA catalysis in many aspects of cell function, including RNA processing and translation. There has been a significant coming together in the field of RNA in recent years and this book offers a compelling review of the whole field to date. Written by leading experts in their field, who in turn review the structural and mechanistic data for all known ribozymes this book is well suited for undergraduates, postgraduates and researchers in catalytic chemistry as well as those in related fields who require a unique overview of the subject.
Ribozymes Provides comprehensive coverage of a core field in the molecular biosciences, bringing together decades of knowledge from the world’s top professionals in the field Timely and unique in its breadth of content, this all-encompassing and authoritative reference on ribozymes documents the great diversity of nucleic acid-based catalysis. It integrates the knowledge gained over the past 35 years in the field and features contributions from virtually every leading expert on the subject. Ribozymes is organized into six major parts. It starts by describing general principles and strategies of nucleic acid catalysis. It then introduces naturally occurring ribozymes and includes the search for new catalytic motifs or novel genomic locations of known motifs. Next, it covers the development and design of engineered ribozymes, before moving on to DNAzymes as a close relative of ribozymes. The next part examines the use of ribozymes for medicinal and environmental diagnostics, as well as for therapeutic tools. It finishes with a look at the tools and methods in ribozyme research, including the techniques and assays for structural and functional characterization of nucleic acid catalysts. The first reference to tie together all aspects of the multi-faceted field of ribozymes Features more than 30 comprehensive chapters in two volumes Covers the chemical principles of RNA catalysis; naturally occurring ribozymes, engineered ribozymes; DNAzymes; ribozymes as tools in diagnostics and therapy, and tools and methods to study ribozymes Includes first-hand accounts of concepts, techniques, and applications by a team of top international experts from leading academic institutions Dedicates half of its content to methods and practical applications, ranging from bioanalytical tools to medical diagnostics to therapeutics Ribozymes is an unmatched resource for all biochemists, biotechnologists, molecular biologists, and bioengineers interested in the topic.
In Therapeutic Applications of Ribozymes, expert laboratory scientists describe in detail their methodologies for constructing ribozymes designed to elucidate the role of specific genes as key routes to the development of novel therapies for a wide variety of diseases. The authors review the many sites targeted with ribozymes in various diseases and provide specific accounts of the practical techniques required for the proper use of ribozymes in these systems. Their cutting-edge protocols demonstrate how to achieve ribozyme expression in distinct cellular systems, the preparation and use of high-efficiency ribozyme DNA or RNA delivery, and the studies required to prove the efficacy of ribozyme-mediated inhibition, with its concomitant effect on phenotypic parameters. Therapeutic Applications of Ribozymes contains all the practical detail necessary to realize the high promise of ribozyme technology as a significant, widely used methodology. Focused on ribozyme targets and the novel associated technology, the book immediately becomes the leading resource for all those seeking to transform this new category of therapeutic agent into efficacious clinical practice.
This special volume of Progress in Molecular Biology and Translational Science focuses on catalytic RNA.

Contributions from leading authorities Informs and updates on all the latest developments in the field
Behind the neologism “ribozymes” lies a family of fascinating molecules, ribo-enzymes, which have been relatively little studied. These catalytically active RNAs are found in all strata of life, from viruses to the human genome. At the end of the 1970s, the discovery of a catalytic RNA nestled in an intron, followed by another involved in the maturation of transfer RNAs, led to the discovery of new ribozymes and the transition from a strictly “proteocentric” vision, inherited from the dogma of molecular biology, to a more “nucleocentric” one. Since then, a variety of ribozymes have been identified in genomes, where their functions often remain mysterious. Looking at Ribozymes traces the discovery of these molecules and presents a picture of their functional diversity, catalytic mechanisms and distribution within the tree of life.
Hepatitis delta virus (HDV), which causes severe acute and chronic liver disease, was discovered nearly 30 years ago following the detection of a novel antigen-antibody system in hepatitis B virus carriers. HDV has continued to surprise and fascinate medical science ever since. This volume reviews recent developments in HDV research, from molecular virology to genetics to experimental investigation of new therapeutic and vaccine candidates.
Ribonucleic acid (RNA) is a macromolecule that plays a central role in cell physiology: RNA molecules act as intermediates between the deoxyribonucleic acid (DNA), where genetic information is stored, and proteins, which perform the necessary functions within the cell. Traditionally, the structural and functional properties of RNA are closely linked to gene expression. However, RNA-based enzymes, called ribozymes, are also involved in catalysis and small RNAs regulate key cellular processes, such as cell growth, division, differentiation, aging and death. RNA is a sensitive macromolecule that can be easily damaged by environmental conditions (ultraviolet radiation, oxidative stress) and biological factors (ribonucleases, ribotoxins, CRISPR-Cas systems). Therefore, cells have developed mechanisms to protect and/or repair RNA molecules. This book presents an overview of the biology of RNA damage, protection and repair in prokaryotes and eukaryotes. Individual chapters cover the expression regulation, enzymology and physiological role of such systems, and link them to important human diseases such as cancer and degenerative diseases.
The discovery of ribozymes nearly 30 years ago triggered a huge interest in the chemistry and biology of RNAs. Much of the recently made progress focusing on metal ions is addressed in MILS 9. This book, written by 28 internationally recognized experts from 8 nations, provides a most up-to-date view and is thus of special relevance for colleagues teaching courses in biological inorganic chemistry and for researchers dealing, e.g., with nucleic acids, gene expression, and enzymology, but also for those in analytical and bioinorganic chemistry or biophysics. Structural and Catalytic Roles of Metal Ions in RNA describes in an authoritative and timely manner in 12 stimulating chapters, supported by nearly 1600 references, 13 tables, and 75 illustrations, mostly in color, metal ion-binding motifs, methods to detect and characterize metal ion-binding sites, and the role of metal ions in folding and catalysis. It deals with diffuse metal ion binding, RNA quadruplexes, the regulation of riboswitches, metal ions and ribozymes, including artificial ribozymes. The spliceosome, the ribosome, ribozymes involving redox cofactors as well as the binding of kinetically inert metal ions to RNA are also covered.
