Phylogenetic analysis of YebC family. Organisms where YebC genes are located very close to RuvABC genes are shown in red. The root node of the tree is shown as a blue dot. Separate branches for the two subtypes of YebC in bacteria and the eukaryotic YebC-like proteins are also shown. Both bootstrap support (the number of times each branch was supported in bootstrap replication) and the measurement of distance for the branch lengths (shown by a bar) are indicated.
