Lack of Specificity in Geobacter Periplasmic Electron Transfer

This is the authors' abstract. We don't add key points for this paper.

Many inner and outer membrane cytochromes used by Geobacter for electron transfer to extracellular acceptors have specific functions. How these are connected by periplasmic carriers remains poorly understood. G. sulfurreducens contains multiple triheme periplasmic cytochromes with unique biochemical properties and expression profiles.
