RNA Polymerases [PDF]

open access: possibleCurrent Protocols in Molecular Biology, 2008
AbstractThis unit describes DNA‐dependent, RNA‐dependent, and template‐independent RNA polymerases. DNA‐dependent RNA polymerases include the related bacteriophage T7, T3, and SP6 polymerases, the most commonly used RNA polymerases for in vitro transcription reactions. Reaction conditions to produce preparative quantities of transcribed RNA and labeled

Viral RNA Polymerase

Critical Reviews in Biochemistry, 1988
Recent progress in molecular biological techniques revealed that genomes of animal viruses are complex in structure, for example, with respect to the chemical nature (DNA or RNA), strandedness (double or single), genetic sense (positive or negative), circularity (circle or linear), and so on.

The genetics of RNA polymerases in yeasts [PDF]

open access: possibleCurrent Genetics, 1990
Over the past few years, substantial progress has been made in the genetic characterization of yeast RNA polymerases. Most of their genes have been identified and their complete cloning and sequencing is within reach. Several conclusions can be drawn at this stage.

Plastid RNA Polymerases

Molecular Biology, 2005
Plastids have a very interesting transcription apparatus that gives us an opportunity to investigate mono- and multisubunut RNA polymerase interaction under conditions of complex biogenesis of the organelles and the necessity to coordinate the expression of genes located in different cell compartments.

T7 RNA Polymerase

2003
Abstract Bacteriophage T7 RNA polymerase (RNAP) is the best characterized member of a widespread family of RNAPs that includes most bacteriophage-encoded RNAPs as well as the mitochondrial RNAPs. The robust activity and strict promoter specificity of the phage RNAPs have made them extremely useful as reagents for both in vitro preparation of ...

Bacterial RNA polymerase

Current Opinion in Structural Biology, 2001
The recently determined crystal structure of a bacterial core RNA polymerase (RNAP) provides the first glimpse of this family of evolutionarily conserved cellular RNAPs. Using the structure as a framework, a consistent picture of protein-nucleic acid interactions in transcription complexes has been accumulated from cross-linking experiments.

RNA Polymerase: Structural Similarities Between Bacterial RNA Polymerase and Eukaryotic RNA Polymerase II

Journal of Molecular Biology, 2000
Bacterial RNA polymerase and eukaryotic RNA polymerase II exhibit striking structural similarities, including similarities in overall structure, relative positions of subunits, relative positions of functional determinants, and structures and folding topologies of subunits.
