Reed,Dmitry A. Rodionov,Jorge L. M. Rodrigues,Daad A. Saffarini,Margrethe H. Serres,Alfred M. Spormann,Igor B. Zhulin,James M. Tiedje +16 more
TL;DR: Systems-level analysis of the model species Shewanella oneidensis MR-1 and other members of this genus has provided new insights into the signal-transduction proteins, regulators, and metabolic and respiratory subsystems that govern the remarkable versatility of the shewanellae.
Current Production and Metal Oxide Reduction by Shewanella oneidensis MR-1 Wild Type and Mutants
Orianna Bretschger,Anna Obraztsova,Carter A. Sturm,In Seop Chang,In Seop Chang,Yuri A. Gorby,Samantha B. Reed,David E. Culley,Catherine L. Reardon,Soumitra Barua,Soumitra Barua,Margaret F.

TL;DR: The results showed that a few key cytochromes play a role in all of the processes but that their degrees of participation in each process are very different, suggesting a very complex picture of electron transfer to solid and soluble substrates by S. oneidensis MR-1.
Characterization of an electron conduit between bacteria and the extracellular environment
Robert S. Hartshorne,Catherine L. Reardon,Daniel E. Ross,Jochen Nuester,Thomas A. Clarke,Andrew J. Gates,Paul C. Mills,James K. Fredrickson,John M. Zachara,Liang Shi,Alexander S. Beliaev,Matthew J. Marshall,Ming Tien,Susan L. Brantley,Julea N. Butt,David J. Richardson +15 more
TL;DR: A spectro-potentiometric characterization of a trans-OM icosa-heme complex, MtrCAB, is presented and its capacity to move electrons across a lipid bilayer after incorporation into proteoliposomes is demonstrated.
c-Type cytochrome-dependent formation of U(IV) nanoparticles by Shewanella oneidensis.
Matthew J. Marshall,Alexander S. Beliaev,Alice Dohnalkova,David W. Kennedy,Liang Shi,Zheming Wang,Maxim I. Boyanov,Barry Lai,Kenneth M. Kemner,Jeffrey S. McLean,Samantha B. Reed,David E. Culley,Vanessa L. Bailey,Cody J. Simonson,Daad A. Saffarini,Margaret F. Romine,John M. Zachara,James K. Fredrickson +17 more
TL;DR: It is shown that c-type cytochromes of a dissimilatory metal-reducing bacterium, Shewanella oneidensis MR-1, are essential for the reduction of U(VI) and formation of extracelluar UO 2 nanoparticles and this is the first study to the authors' knowledge to directly localize the OM-associated cyto Chromes with EPS, which contains biogenic UO2 nanoparticles.
Structure of a bacterial cell surface decaheme electron conduit
Thomas A. Clarke,Marcus J. Edwards,Andrew J. Gates,Andrea Hall,Gaye F. White,Justin M. Bradley,Catherine L. Reardon,Liang Shi,Alexander S. Beliaev,Matthew J. Marshall,Zheming Wang,Nicholas J. Watmough,James K. Fredrickson,John M. Zachara,Julea N. Butt,David J. Richardson +15 more
TL;DR: The structure of one of these decaheme cytochromes, MtrF, is presented, which provides molecular insight into how reduction of insoluble substrate, soluble substrates, and cytochrome redox partners might be possible in tandem at different termini of a trifurcated electron transport chain on the cell surface.
