Figure 2
Structural details of the Pol II elongation complex. (a) Overview of the EC structure (Kettenberger et al., 2004  ). The view is as in Fig. 1(a). (b) Superposition of NTP-binding sites [red, insertion site (Westover et al., 2004a; Wang et al., 2006); violet, entry site (Westover et al., 2004a); pink, inactive pre-insertion-like state in which the triphosphate is too far from the catalytic metal ion A to allow incorporation (Kettenberger et al., 2004)]. (c) Functional Pol II surface elements in the EC highlighted in yellow. This figure was adapted from Cramer et al. (2008). |
