Class Ib RNR protein phylogenies. Phylogenetic trees constructed by the Maximum likelihood method (PhyML) based on the aligned amino acid sequences of a)nrdE and b)nrdF. The phages and bacterial hosts (both taxon labels and nodes) are color coded in green and red, respectively. The bootstrap values are shown for nodes with ≥ 70% support. The scale bar represents the number of amino acid substitutions per site.
