Phylogenetic tree of Mutator superfamily proteins. The cladogram was generated by neighbor-joining, from an alignment of three conserved amino acid motifs present in all sequences (length = 123 residues), and which corresponds to pfam00872 (COG3328 and CDD85084). The sequences are identified by the host names, GenInfo Identifier (gi) and TE names, when previously characterized. Node support obtained from 1,000 bootstrap replicates using NJ and from their representation in the posterior sample of the bayesian analysis is shown above and below the branches, respectively. Gray arrows indicate the four main clades in the Mutator phylogeny.
