Evolution of the B-Block Binding Subunit of TFIIIC That Binds to the Internal Promoter for RNA Polymerase III
Figure 3
Highly schematized cartoon showing distribution of the archaeal B-block binding subunit sequence in the eukaryotic subunit. Colored regions in the eukaryotic subunit correspond to those in Figure 1. Based on all of the results shown in Figure 2 and Supplementary Figure 1, the archaeal subunits (shown as arrows) are placed below the eukaryotic subunit. Arrows are colored more intensely where BLAST hits were frequently detected with lower -values.
