Since structural information is limited to bacterial and eukaryotic RNAPs, we determined the cryo-electron microscopic structure of the RNAP from the thermophilic archaeon Pyrococcus furiosus at 13 A resolution. Comparison with eukaryotic RNAP II reveals a conserved architecture, no homologues for subunits Rpb8 and Rpb9, and significant deviation in the polymerase foot, jaws, pore, and protrusion. The structural organization of the archaeal RNA polymerase serves as a reference for future structure-function analysis of the transcription mechanism and allows for evolutionary comparisons. |
