FIGURE 1: The role of EF-P in M. aeruginosavorus during host invasion. The far left panel depicts P. aeruginosa drawn in purple and M. aeruginosavorus in yellow.

(A) The image illustrates a breach in the outer membrane allowing for dTDP-L-rhamnose to diffuse into M. aeruginosavorus where EF-P (red) is then modified by EarP (white).

(B) As a result of EF-P being modified ribosomes (grey and purple) can effectively translate mRNA (blue) with a poly-proline stretch.

(C) On the other hand during the attack phase EF-P is unmodified and therefore poly-proline translation is absent.
