两个同源的硫还原地杆菌c型细胞色素基因omcG和omcH的缺失，降低了铁（III）还原的速率，降低了铁（III）还原的关键外膜细胞色素OmcB的水平，而不影响其转录。两种基因的表达均恢复了Fe（III）还原和OmcB表达，表明功能相似。
Deletion of two homologous Geobacter sulfurreducens c-type cytochrome genes, omcG and omcH, decreased the rate of Fe(III) reduction and decreased the level of an outer membrane cytochrome critical for Fe(III) reduction, OmcB, without affecting its transcription. Expression of either gene restored Fe(III) reduction and OmcB expression, suggesting functional similarity.
