Fine Tuning of Redox Networks on Multiheme Cytochromes from Geobacter sulfurreducens Drives Physiological Electron/Proton Energy Transduction
Figure 2
Heme oxidation fractions for 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. The order of oxidation of the hemes is indicated by the arrow.
