FIG 6.

Intracellular localization of the scytonemin monomer in induced ΔscyE and ΔeboC cells. Overlay of the 665-nm images over the 410-nm images demonstrates the localization of the scytonemin monomer in the cytoplasm of ΔeboC cells (this was the case for each and all of the ebo mutants, as can be seen in Fig. S2). In ΔscyE cells; however, the scytonemin monomer accumulates in both the cytoplasm and the periplasm.
