Figure 3: Normalized spectral counts of the EzrA-containing protein and its maximum likelihood phylogeny.

(a) Shown are the EzrA-containing protein abundances across treatments. Colour key as in Fig. 1; squares indicate significance relative to the replete 380 and triangles relative to both the replete 750 and 380. Error bars are s.e. (b) Maximum likelihood phylogeny of detected protein homologues in NCBI (Methods) to the IMS101 EzrA-containing protein, with the Staphylococcus EzrA protein as the outgroup. Bootstrap values ≥50 are noted.
