abstract = {A novel concept is introduced for the oriented
incorporation of membrane proteins into solid supported
lipid bilayers. Recombinant cytochrome c oxidase solubilized
in detergent was immobilized on a chemically modified gold
surface via the affinity of its histidine-tag to a
nickel-chelating nitrilo-triacetic acid (NTA) surface. The
oriented protein monolayer was reconstituted into the lipid
environment by detergent substitution. The individual steps
of the surface modification, including (1) chemical
modification of the gold support, (2) adsorption of the
protein, and (3) reconstitution of the lipid bilayer, were
followed in situ by means of surface-enhanced infrared
absorption spectroscopy (SEIRAS) and accompanied by
normal-mode analysis. The high surface sensitivity of SEIRAS
allows for the identification of each chemical reaction
process within the monolayer at the molecular level.
Finally, full functionality of the surface-tethered
cytochrome c oxidase was demonstrated by cyclic voltammetry
after binding of the natural electron donor cytochrome c.},
