RNA polymerase - Wikipedia
In molecular biology, RNA polymerase (abbreviated RNAP or RNApol), or more specifically DNA-directed/dependent RNA polymerase (DdRP), is an enzyme that catalyzes the chemical reactions that synthesize RNA from a DNA template.
Crystal structure of a DNA-dependent RNA polymerase (DNA …
We have solved the crystal structure of the catalytic primase subunit from the hyperthermophilic archaeon Pyrococcus furiosus at 2.3 Å resolution by multiwavelength anomalous dispersion methods....
Structure and Function of DNA-dependent RNA-Polymerase
RNA-Polymerase = enzyme of transcription in vivo: The transcription of the genetic information of the DNA-base-sequences into RNA-structure is performed by the DNA-dependent RNA-polymerase [1, 2]. This enzyme has been highly purified from E. coli [3].
sequences into RNA-structure is performed by the DNA-dependent RNA-polymerase [1,2]. This enzyme has been highly purified from E. coli [3]. It catalyses the synthesis of RNA in vitro in the pres ence of a DNA-template and the 4 ribonucleoside-triphosphates. The requirements for the reaction are shown in the first figure (Fig. 1). n¥ATP} n ...

2013年11月11日 · However, the DNA-dependent RNA polymerase proved elusive until 1960 when it was independently identified in bacteria by Hurwitz and Stevens and in plants by the Bonner group 5. Later, investigations focused on mechanisms of RNA polymerization established that synthesis was not monotonous.
