Figure 2.
Fig. 2. Backbone model of complete, 12-subunit pol II.
Shown is a ribbon representation of the complete pol II
structure (top and back views as in refs. 10 and 11). Rpb1 is
gray, Rpb2 is bronze, Rpb4 is red, Rpb6 is green, the N-terminal
half of Rpb7 that contains the RNP domain is dark blue, the
C-terminal half of Rpb7 that contains the OB fold is light blue,
and the remaining subunits are black. The locations of the
clamp, the C-terminal repeat domain (CTD), and the previously
proposed RNA exit groove 1 (pink dashed line) are indicated. The
figure was generated with SWISS-PDB VIEWER and POV-RAY (40).
