MD simulations of WT and Y27A pili. (A,B) Snapshots of the geometry-optimized WT (A) and Y27A (B) pilus model (black, Y27; orange, other aromatic residues) and detail of aromatic clusters with inter-aromatic distances. (C,D) 3D-projection of aromatic density (C), aromatic contacts (D), and electrostatic surface map (E) of WT and Y27A pili.
A microbial protein fiber discovered by a Michigan State University scientist transports charges at rates high enough to be applied in humanmade nanotechnologies. The discovery describes the high-speed protein fiber produced by uranium-reducing Geobacter bacteria. The fibers are hair-like protein filaments called “pili” that have the unique property of transporting charges at speeds of 1 billion electrons per second.
“This microbial nanowire is made of ...
