FIG. 5.
Copurification of MtrC with OmcA. Heme staining (lanes 1 to 3) and immunoblot assays against MtrC (lanes 4 to 6) following separation by SDS-PAGE of purified recombinant OmcA (rOmcA) isolated from either wild-type (lanes 1 and 4) or ΔomcA mtrC double-mutant (lanes 2 and 5) S. oneidensis MR-1 cells. The enriched membrane of wild-type S. oneidensis MR-1 cells (lanes 3 and 6) was used as a control.
