Phylogeny of all CLS_cap from eukaryotes and bacteria, and PGPS homologs of bacteria. Tree was inferred using MrBayes 3.12 on aligned amino acid dataset. Numbers at the nodes correspond to Bayesian posterior probabilites ≥ 0.50 (at the left of slashes) and the bootstrap value of ML tree (at the right of slashes). Scale bar indicates number of change per site. Bacterial PGPS are condensed as a triangle clade and rooted as outgroup.
