Abundances of selected classes of copper-related proteins (RND HME in A, Cu ATPase in B and CusF in C) in β proteobacteria as a function of their lifestyles. Absolute numbers are shown here, and the horizontal orange lines represent the medians of the values for each group. E, environmental bacteria; OE, opportunistic/environmental bacteria; C, commensal bacteria; OC, opportunistic/commensal bacteria; AP, animal pathogens; PP, phytopathogens; EnP, endophytes; S, symbionts; EnS, endosymbionts. The orange horizontal lines represent the medians of the values for the various groups.
