Figure 2.
Surface representations of cellular RNAP structures from bacteria (left, Thermus aquaticus core enzyme), archaea (center, Sulfolobus solfataricus RNAP), and eukaryote (right, Saccharomyces cerevisiae Pol II). Each subunit is denoted by a unique color and labeled. Orthologous subunits are depicted with the same color. Color version of the figure is available online.
