Magnetite compensates for the lack of a pilin‐associated c ‐type cytochrome in extracellular electron exchange
Abstract
Summary: Nanoscale magnetite can facilitate microbial extracellular electron transfer that plays an important role in biogeochemical cycles, bioremediation and several bioenergy strategies, but the mechanisms for the stimulation of extracellular electron transfer are poorly understood. Further investigation revealed that magnetite attached to the electrically conductive pili of G eobacter species in a manner reminiscent of the association of the multi‐heme c ‐type cytochrome OmcS with the pili of G eobacter sulfurreducens . Magnetite conferred extracellular electron capabilities on an OmcS ‐deficient strain unable to participate in interspecies electron transfer or Fe ( III ) oxide reduction. In the presence of magnetite wild‐type cells repressed expression of the OmcS gene, suggesting that cells might need to produce less OmcS when magnetite was available. The finding that magnetite can compensate for the lack of the electron transfer functions of a multi‐heme c ‐type cytochrome has implications not only for the function of modern microbes, but also for the early evolution of microbial electron transport mechanisms.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
