Phylogenetic tree of full length prokaryotic and eukaryotic ArsA homologues. The CLUSTAL X program [23] was used to create a multiple alignment of the protein sequences, while TreeView [24] generated the tree. The phylogenetic clusters are labeled 1–18 clockwise. Specific proteins can be found in Table 1, first according to cluster number and then according to position within the cluster. The dendrogram is shown in Figure S1.
