免疫金定位显示，OmcS（一种硫还原地杆菌还原 Fe(III) 氧化物所需的细胞色素）沿着菌毛定位。 OmcS 分子之间的明显间距表明 OmcS 促进电子从菌毛转移到 Fe(III) 氧化物，而不是促进电子沿菌毛长度传导。
Immunogold localization revealed that OmcS, a cytochrome that is required for Fe(III) oxide reduction by Geobacter sulfurreducens, was localized along the pili. The apparent spacing between OmcS molecules suggests that OmcS facilitates electron transfer from pili to Fe(III) oxides rather than promoting electron conduction along the length of the pili.
