抗体识别力显微镜显示，当 Fe(III)（包括固相赤铁矿 (Fe(2)O(3)））为末端电子受体时，OmcA 和 MtrC 在活体 Shewanella oneidensis MR-1 细胞的外表面表达。 OmcA 定位于细胞和矿物质之间的界面。 MtrC 在细胞表面显示出更均匀的分布。两种细胞色素都与细胞外聚合物相关。
Antibody recognition force microscopy showed that OmcA and MtrC are expressed on the exterior surface of living Shewanella oneidensis MR-1 cells when Fe(III), including solid-phase hematite (Fe(2)O(3)), was the terminal electron acceptor. OmcA was localized to the interface between the cell and mineral. MtrC displayed a more uniform distribution across the cell surface. Both cytochromes were associated with an extracellular polymeric substance.
