Figure 3.
Fig. 3. Relationship of complete pol II x-ray structure to
EM structures of complete pol II (A) and Mediator-pol II complex
(B). As this complex was prepared from exponentially growing
yeast, it would have been largely deficient in Rpb4/Rpb7,
accounting for the lack of density in this region of the EM map.
The core pol II model is blue in A and yellow in B. Rpb4 is red
and Rpb7 is dark blue. The figure was generated by using O and
POV-RAY (19).
