Phylogenetic analysis of 17 putative ABC transporters from the isolated strains with 23 reference sequences of ABC transporters described in actinobacteria. The phylogeny was inferred by Bayesian analysis of amino-acid sequence alignment. Branch lengths correspond to mean posterior estimates of evolutionary distances (scale bar, 0.5). Branch labels indicate the Bayesian posterior probability and supporting bootstrap values from maximum-likelihood and neighbor-joining analyses for branches with significant support and relevance for clustering of the analyzed sequences.
