Figure 8

Unrooted phylogenetic tree (radial view) of the SstT family of transport genes. The data analysis was performed as described in the legend for Figure 7. The experimentally documented SstT proteins of serine transport in E. coli (Eco) and Porphyromonas gingivalis (Pgin) are highlighted in yellow. Bootstrap values at the major node positions are shown, and those nodes supported by 1,000 of 1,000 iterations are denoted with blue circles. See Table 2 for organism acronyms and gene identification numbers.
