    Bacteria 'nanowires' could help develop green electronics
    Structure of γPFD filaments and incorporation of heme to make conductive nanowires. a) Filament assembly of γPFD through β-sheet domains, and b) proposed binding of heme molecules to the coiled-coil domains to form γPFD-heme nanowires. c) Protein-ligand binding isotherm with 30 µm of γPFD and varying concentration of heme, which indicates a stochiometric ratio of ≈1 heme per γPFD subunit in filaments. d) TEM image of the γPFD-heme nanowires.
