Mineral-respiring microorganisms from hydrothermal vents to terrestrial soils express filaments that electrically connect intracellular respiration extracellular geochemistry. Filaments dubbed “cytochrome nanowires” (CNs) have been resolved by CryoEM, but whether they are the two-decades-long sought-after physiological “nanowires” remains unproven. To assess their functional competence, we analyzed biological redox conduction in all CNs computing driving forces presence of anti-cooperativities, reorganization energies with electronic polarizability, and Marcus rates for diffusive protein-limited flux models. The chain heme cofactors any CN must be densely packed realize weak (≤0.01 eV) coupling electron transfer, as evidenced a single Soret band produced coincidental absorptions on multiple hemes. Dense packing, turn, has three consequences: (1) limited (≤|0.3| due shared electrostatic microenvironments, (2) strong (≤0.12 anti-cooperativities would accentuate free energy landscape if linear arrangement did not dictate contra-thermodynamic oxidation order, (3) an entropic penalty is offset thioether ‘tethers’ hemes protein backbone. These linkages physically necessitate rate-throttling T-stacked motif (10-fold slower than other highly conserved slip-stacked motif). If sequence slip- had fastest known nanosecond at every step, micron-long filament carry 0.02 pA current 0.1 V, or 0.2 pA. Actual sub-optimal (≤10 2 -fold lower), sufficient conductivities cellular respiration, most thousands needed total metabolic flux. Reported once used argue metallic-like pili against cytochrome hypothesis now attributed remain inconsistent 10 –10 5 physical constraints through multiheme architectures.
