WebRNA polymerase II (RNAPII) is a 12-subunit enzyme which synthesizes all mRNAs as well as several non-coding RNAs in eukaryotic cells thereby playing a central role in cellular functions. RNAPII is a DNA-dependent RNA polymerase enzyme which catalyzes the transcription of DNA into RNA employing four ribonucleoside triphosphates as substrates. WebDespite variation in structure and subunit composition, RNA pols from different organisms harbors conserved features Darst 2010a and2010b). The article by Lei and Burton compares the three-dimensional structure of archaeal, bacterial and eukaryotic RNA pols.
