Figure 1. The modular nature of SAGA supports multiple activities.

Figure 1

Subunits within the different modules of S. cerevisiae SAGA are indicated by different colors: acetyltransferase (blue), ubiquitin protease (orange), TAF (pink), Spt (purple) and Tra1 (green). The relative molecular weight of each subunit is indicated by the area of the circle. Subunits that are more central to the complex are shown within the inner box, and peripheral subunits are shown inside the outer box. Different functions of individual subunits are indicated by the arrows and text. Probable physical connections between subunits are indicated by dotted lines.
