FIG 4.

CvpA is highly conserved across many bacterial phyla. (a) Phylogeny of CvpA distribution across bacterial phyla. Pink lines represent phyla where at least one species has a CvpA homolog with at least 30% amino acid identity and at least 70% alignment to E. coli CvpA. The numbers shown in brackets denote the number of individual genomes in that phylum. (b) Phyla with various degrees of CvpA conservation at the species level. Pink lines represent species that contain a CvpA homolog. Numbers in parentheses after phylum names indicate the percentages of species in those phyla with a CvpA homolog.
