One or more of five morphologically distinct classes of appendage pili were determined to
be peritrichously expressed by Burkholderia (formerly Pseudomonas) cepacia isolated from …

Geobacter sulfurreducens generates electrical current by coupling intracellular oxidation of
organic acids to the reduction of proteins on the cell surface that are able to interface with …

Prokaryotes have engineered sophisticated surface nanomachines that have allowed them
to colonize Earth and thrive even in extreme environments. Filamentous machineries …

Immunogold localization revealed that OmcS, a cytochrome that is required for Fe (III) oxide
reduction by Geobacter sulfurreducens, was localized along the pili. The apparent spacing …

The bacterial type IV pilus (T4P) is the strongest biological motor known to date as its
retraction can generate forces well over 100 pN. Myxococcus xanthus, a δ-proteobacterium …

Bacterial type IV pili perform important functions in such disparate biological processes as
surface adhesion, cell–cell interactions, autoaggregation, conjugation, and twitching motility …

Syntrophic interspecies electron exchange is essential for the stable functioning of diverse
anaerobic microbial communities. Hydrogen/formate interspecies electron transfer (HFIT), in …

In both bacteria and Archaea, the biosynthesis of type IV pilus-related structures involves a
set of core components, including a prepilin peptidase that specifically processes precursors …

Background Geobacter species are δ-Proteobacteria and are often the predominant species
in a variety of sedimentary environments where Fe (III) reduction is important. Their ability to …

Electrically conductive protein nanowires appear to be widespread in the microbial world
and are a revolutionary “green” material for the fabrication of electronic devices. Electrically …
