RNA polymerase III (Pol III) transcribes short RNAs required for cell growth. Under stress conditions, the conserved protein Maf1 rapidly represses Pol III transcription. We report the crystal structure of Maf1 and cryo-electron microscopic structures of Pol III, an active Pol III-DNA-RNA complex, and a repressive Pol III-Maf1 complex.

Related multisubunit RNA polymerases (RNAPs) carry out gene transcription in all kingdoms of life. 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.
