Book Description
This book follows on from Volume 83 in the SCBI series (“Macromolecular Protein Complexes”), and addresses several important topics (such as the Proteasome, Anaphase Promoting Complex, Ribosome and Apoptosome) that were not previously included, together with a number of additional exciting topics in this rapidly expanding field of study. Although the first SCBI Protein Complex book focused on soluble protein complexes, the second (Vol. 87)addressed Membrane Complexes, and the third (Vol. 88) put the spotlight on Viral Protein and Nucleoprotein Complexes, a number of membrane, virus and even fibrillar protein complexes have been be considered for inclusion in the present book. A further book is also under preparation that follows the same pattern, in an attempt to provide a thorough coverage of the subject.

Book Description
To thrive, every living cell must continuously gauge and respond to changes in its environment. These changes are ultimately implemented by modulating gene expression, a process that relies on transcription by Nature’s most multivalent molecular machine, the RNA polymerase. This book covers progress made over the past decade understanding how this machine functions to compute the cellular state, from the atomistic structural level responsible for chemistry to the integrative level at which RNA polymerase interacts with the other key molecular machineries of the cell.

Book Description
Presents a coherent account of many productive lines of investigation, organized as a series of mini-reviews that focus on major research areas including studies on the structure and mechanisms of action of bacterial, viral, and eukaryotic RNA polymerases, and the transcription factors that control their activities. Each review provides a brief but up-to-date account of the progress of research in a particular area, a discussion of the major issues and questions driving that research, and a brief description of the evolving approaches and technologies used to address those questions.

Book Description
This monograph reviews and summarizes the substantial body of work that has been published on the transcription by polymerase III over the past 5 years. Progress in this field has been very rapid since 1993, and this new edition incorporates all the recent developments and offers the reader a highly detailed analysis of the current state of research on this largest and most complex of the eukaryotic RNA polymerases.

Book Description
Proceedings of a summer 1998 meeting, presenting results of recent studies in gene transcription. Covers events ranging from activation, through promoter recognition, repression, chromosome structure, chromatin remodeling, initiation and elongation, and regulatory complexes and pathways. Subjects include targeting sir proteins to sites of action, the yeast RNA polymerase III transcription machinery, nuclear matrix attachment regions to confer long-range function on immunoglobulin, ATP-dependent remodeling of chromatin, and the transcriptional basis of steroid physiology.

Book Description
Transcription of genomic DNA of all organisms is carried out by members of the multi-subunit RNA polymerase family. Regulation of RNA polymerase localization and activity underlies cellular homeostasis, division, and response to environmental cues. The catalytic mechanism, overall architecture, and many sequence and structural features of bacterial RNA polymerase are conserved in its Archaeal and Eukaryotic counterparts. The human RNA polymerase II (Pol II) is responsible for transcription of all protein-coding and many non-coding genes. The majority of current knowledge on RNA polymerases and their mechanism at different steps in transcription derives from extensive work done using classical biochemical, genetic and structural biology methods. However, the use of single-molecule approaches addressed crucial questions on the function and mechanism of RNA polymerases during transcription, which were not possible to answer with ensemble-based approaches due to averaging effects. A useful fluorescence-based single-molecule technique to measure distances on the molecular scale and monitor dynamics is F rster resonance energy transfer (FRET). Here, I report on the development of diffusion-based single-molecule FRET (smFRET) methods to investigate different steps in transcription by the in vitro reconstituted human Pol II system. Using an assay that monitors the FRET changes between fluorescent dyes in the unwound region of promoter DNA (transcription bubble), I demonstrated the effect of certain components of the reconstituted system on the relative size of the transcription bubble. I also detail the optimizations done to enhance the affinity of single-stranded DNA (ssDNA) FRET probes to complementary target sequences. These ssDNA FRET probes were used to investigate the effect of certain components of the reconstituted system on Pol II activity by measuring the relative levels of RNA product. In addition to studies on the Pol II system, I report on the effect of the 5'-group of nascent RNA on the stability of the Escherichia coli RNA polymerase (RNAP) transcription bubble. I show how the presence of a 5'-monophosphate appears to destabilize the open bubble while a 5'-hydroxyl has no effect. Finally, I describe the work done on a project I took part in that identified a previously uncharacterized RNAP paused complex in initiation. We demonstrate that RNAP complexes undergoing initial transcription can enter the inactive paused state by backtracking. I also demonstrate how the presence of a 5'-triphosphate rapidly enhances entrance of RNAP complexes undergoing initial transcription into an inactive paused complex.
