Class II and III RNR protein phylogenies. Phylogenetic trees constructed by the Maximum likelihood method (PhyML) based on the aligned amino acid sequences of a)nrdJ: the collapsed clades include:
    Cyanobacteria spp.
(Prochlorococcus marinus, Synechococcus sp. PCC 7335 G and WH 7803),
    Mycobacteriophages
(Airmid, Backyardigan, Benedict, Bxz2, Che12, D29, DaVinci, Eagle, EricB, George, Gladiator, Hammer, JHC117, Microwolf, PackMan, Peaches, Pukovnik, RedRock, Rockstar, Shaka, and Vix),
    Mycobacteria spp.
(Mycobacterium sp. MCS and M. tuberculosis),
    Pseudomonas
      phages
    (YuA and M6),
      Roseophages
    (DSS3P2 and EE36P1), and
      Thermus
        phages
      (P23-45, P74-26, and phiYS40), and b)nrdD: the collapsed clades includes
        Aeromonas
        phage cluster 1
      (Aeh1, phiAS5, and PX29),
        Aeromonas
          phage cluster 2
        (25, 31, 44RR2.8 t, and phiAS4), A
          eromonas
          spp.
        (A. hydrophila and salmonicida),
          Enterobacteria phage cluster 1
        (RB51, RB14, and RB32),
          Enterobacteria phage cluster 2
        (Phi1, RB49, and JSE),
          Enterobacteria phage cluster 3
        (RB16 and RB43),
          Enterobacteria phage cluster 4
        (EPS7, SPC35, and T5),
          Enterobacteria phage cluster 5
        (T4 and T4T), and
          Vibrio
          spp.
        (V. cholerae and parahaemolyticus). 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.
