Cells with the ''omcS'' gene deleted (''ΔomcS'') produced thinner (~1.7 nm) filaments that were smooth (not sinusoidal) and had electrical conductivity >100-fold lower than the OmcS filaments. ''ΔomcS'' cells can produce electrically conductive biofilms, but that conductivity might well depend on filaments of OmcZ, whose expression is known to increase in ''ΔomcS'' cells. | Cells with the ''omcS'' gene deleted (''ΔomcS'') produced thinner (~1.7 nm) filaments that were smooth (not sinusoidal) and had electrical conductivity >100-fold lower than the OmcS filaments.

Previous studies showed that PilA is required for export of OmcS. However, PilA was not found in the | Previous studies showed that PilA is required for export of OmcS. However, PilA was not found in the structure of the OmcS nanowires studied here. Thus, PilA appears to be required for production of OmcS nanowires, but not to be a structural component of those nanowires. | ||
