Solubilization of the TorC cytochrome under mild conditions. Peroxidase activity of c type hemes of cytochromes from membranous and membrane extracted proteins of S. oneidensis wild type cells (WT) or ΔtorE deletion mutant (ΔE) either after 2% DDM solubilization or 1.5 M NaBr. Ten microgram proteins were loaded in each lane of the 3–14% SDS gel. After electrophoresis, c-type cytochromes were revealed by their peroxidase activity. TorC is indicated by an arrow. **T test analysis performed by GraphPad Prism Software shows that data from three replicates are significantly different (p = 0.0058). No band can be detected in the WT lanes for three replicated experiments, preventing statistical analyses Separated portions of the same blots are represented with their respective molecular weight markers (see Figure S2).
