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

Figure 4

Dependence of the molar fractions of PpcA and PpcD microstates with pH and solution potential (versus SHE) at 288 K and 250 mM ionic strength. The molar fractions of the individual microstates were determined using the parameters listed in Table 1, and those showing the largest molar fraction are represented. The regions where proteins can perform transfer and transfer are highlighted in dark gray and gray, respectively. Regions where the protein is fully reduced or fully oxidized are indicated in light gray.
