The X-ray crystal structure of Shewanella oneidensis OmcA reveals new insight at the microbe–mineral interface (original) (raw)

The crystal structure of Shewanella oneidensis OmcA has been determined to a resolution of 2.7 Å, revealing insights into the molecular mechanisms underlying electron transfer processes at the microbe-mineral interface. The research highlights the architecture of OmcA and its interactions with extracellular minerals, particularly focusing on the arrangement of OmcA dimers and their role in facilitating electron transfer to Fe(III) minerals. By comparing the structure of OmcA with other multi-heme cytochromes, the study advances the understanding of electron transport in metal-reducing bacteria.
