Figure 5.

The Bayesian tree of the DUS family. Sequences are indicated by the abbreviated genus and species name (e.g. Bacsub for B. subtilis) and the NCBI GI number and their phylogenetic origin are indicated. For clarity of the presentation, branches with sequences belonging to the same taxa have been collapsed and are shown as triangles. Values at the nodes indicate the statistical support for the particular branches, according to the bootstrap test.
