Fine Tuning of Redox Networks on Multiheme Cytochromes from Geobacter sulfurreducens Drives Physiological Electron/Proton Energy Transduction

Figure 3

Molar fraction of the 16 individual microstates (see Figure 1) of PpcA (a) and PpcD (b) at different pH values. The curves were calculated as a function of the solution reduction potential (versus SHE) using the parameters listed in Table 1. Solid and dashed lines indicate the protonated and deprotonated microstates, respectively. For clarity, only the relevant microstates are labeled.
