Bottom-Up Fabrication of Protein Nanowires via Controlled Self-Assembly of Recombinant
mBio, 2019 Metal-reducing bacteria in the genus Geobacter use a complex protein apparatus to guide the self-assembly of a divergent type IVa pilin peptide and synthesize conductive pilus appendages that show promise for the sustainable manufacturing of protein ...

Lack of physiological evidence for cytochrome filaments functioning as conduits for extracellular electron transfer [PDF]
mBioExtracellular cytochrome filaments are proposed to serve as conduits for long-range extracellular electron transfer. The primary functional physiological evidence has been the reported inhibition of Geobacter sulfurreducens Fe(III) oxide reduction when ...

The electrically conductive pili of Geobacter species are a recently evolved feature for extracellular electron transfer. [PDF]
Microb Genom, 2016 The electrically conductive pili (e-pili) of Geobactersulfurreducens have environmental and practical significance because they can facilitate electron transfer to insoluble Fe(III) oxides; to other microbial species; and through electrically conductive biofilms. E-pili conductivity has been attributed to the truncated PilA monomer, which permits tight

The electrically conductive pili of Geobacter soli [PDF]
, 2020 Abstract Electrically conductive pili (e-pili) enable electron transport over multiple cell lengths to extracellular environments and play an important role in extracellular electron transfer (EET) of Geobacter species. To date, the studies of e-pili have mainly focused on

The Role of Exopolysaccharides in Direct Interspecies Electron Transfer
Frontiers in Microbiology, 2022 Direct interspecies electron transfer (DIET) is an effective mechanism for microbial species to exchange electrons cooperatively during syntrophic metabolism. It is generally accepted that DIET is mainly mediated by electrically conductive pili and outer
