Arguments Reinforcing the Three-Domain View of Diversified Cellular Life

Figure 2

Functional composition of AE, BE, and EV Venn groups. FSFs were mapped to one of the seven major functional categories of molecular functions (i.e., Metabolism, Information, Regulation, Intracellular Processes, Extracellular Processes, General, and Other), as defined by Christine Vogel (http://supfam.org/SUPERFAMILY/function.html) [47–49]. Numbers on the right indicate total number of FSFs for which functional annotation was available. Numbers on bars indicate total number of FSFs annotated to each of the seven major functional categories in that group.
