We show that the αK helix could be also used in the form of a synthetic biotinylated peptide to target a labelled streptavidin complex to Golgi membranes in fixed, permeabilized cells.

To build the 4-nm-diameter molecular robot, the researchers started with a common protein called streptavidin, which has four symmetrically placed binding pockets for a chemical moiety called biotin.
-
The scientists then coated the micrometer-long, pear-shaped bacteria with a solution containing biotin, a vitamin that readily binds to streptavidin.

The researchers laid down fetuin within the circular groove and coated the rotor with a protein called streptavidin.

As the microbes passed each of a rotor's supporting ridges, their biotin-treated cell membranes clung to the streptavidin coating, causing tugs on the tabs and thereby turning the rotor.
