Abstract
Improved electrically conductive pili were generated from a natural pilus protein from the microorganism. Substituting a tryptophan for the phenylalanine at position F51 and a tryptophan for the tyrosine at position Y57 of the pilus monomer substantially increased the conductivity of the pili and reduced their diameter to 1.5 nm. Substantial improvements in conductivity were also achieved by substituting an additional tyrosine, histidine, and phenylalanine in the pilus monomer to mimic the monomer of, but the pili retained the typicalwild-type diameter of 3 nm.
