Functional Promiscuity of Homologues of the Bacterial ArsA ATPases
Figure 2
Phylogenetic trees showing the coevolution of (a) CstA and (b) ArsA homologues, (c) CstA and (d) CstX homologues, and (e) ArsA and (f) CstX homologues, each pair being encoded within the same operons. The methodology was as described in Figure 1. Cluster numbers are assigned counterclockwise in (b) and retained in (a). Paralogues are distinguished with a second digit, either 1 or 2, in the protein abbreviations.
