Maximum likelihood phylogeny of the 120 Streptomyces strains used in this study. Phylogeny is based on concatenated AtpD and RpoB amino acid sequences. Bootstrap values >50 % are indicated at their respective nodes (based on 100 replicates). Colors indicate the number of ABBA PTases found in each genome. The MAR4 and S. coelicolor clades are indicated. Sequences derived from two Pseudonocardia genomes were used to root the tree
