[https://www.uniprot.org/uniprot/OMCS_GEOSL OMCS_GEOSL] Plays an important role in extracellular electron transfer. Can transfer electrons to insoluble Fe(3+) oxides as well as other extracellular electron acceptors, including Mn(4+) oxide and humic substances (PubMed:16332857, PubMed:20400557, PubMed:21236241). Essential for direct interspecies electron transfer (DIET) in cocultures with G. metallireducens (PubMed:23377933).<ref>PMID:16332857</ref> <ref>PMID:20400557</ref> <ref>PMID:21236241</ref> <ref>PMID:23377933</ref>

== Publication Abstract from PubMed ==
 +
Electrically conductive pili from Geobacter species, termed bacterial nanowires, are intensely studied for their biological significance and potential in the development of new materials. Using cryo-electron microscopy, we have characterized nanowires from conductive G. sulfurreducens pili preparations that are composed solely of head-to-tail stacked monomers of the six-heme C-type cytochrome OmcS. The unique fold of OmcS - closely wrapped around a continuous stack of hemes that can serve as an uninterrupted path for electron transport - generates a scaffold that supports the unbranched chain of hemes along the central axis of the filament. We present here, at 3.4 A resolution, the structure of this cytochrome-based filament and discuss its possible role in long-range biological electron transport.
