COMPLETE 12-SUBUNIT RNA POLYMERASE II AT 3.8 ANG
Overview
We determined the x-ray structure of the RNA polymerase (Pol) II, subcomplex Rpb4/7 at 2.3 A resolution, combined it with a previous, structure of the 10-subunit polymerase core, and refined an atomic model, of the complete 12-subunit Pol II at 3.8-A resolution. Comparison of the, complete Pol II structure with structures of the Pol II core and free, Rpb4/7 shows that the core-Rpb4/7 interaction goes along with formation of, an alpha-helix in the linker region of the largest Pol II subunit and with, folding of the conserved Rpb7 tip loop. Details of the core-Rpb4/7, interface explain facilitated Rpb4/7 dissociation in a, temperature-sensitive Pol II mutant and specific assembly of Pol I with, its Rpb4/7 counterpart, A43/14. The refined atomic model of Pol II serves, as the new reference ... [(full description)]
