abstract = {We present a novel infrared method to investigate the
functionality of a protein monolayer tethered to a metal
substrate. The approach employs Surface Enhanced Infrared
Absorption Spectroscopy (SEIRAS), which renders high surface
sensitivity by enhancing the signal of the adsorbed protein
by up to approximately 2 orders of magnitude. We demonstrate
that the electrochemically induced absorption changes of a
cytochrome c monolayer can be observed with excellent
signal-to-noise ratio when the protein is adhered to a
modified gold surface. To probe membrane proteins, a concept
is introduced for the oriented incorporation into solid
supported lipid bilayers. Recombinant cytochrome c oxidase
solubilized in detergent is immobilized on a chemically
modified gold surface via the affinity of its histidine
(His)-tag to a nickel-chelating nitro-triacetic acid (NTA)
surface. The protein monolayer is reconstituted into the
lipid environment by detergent removal. Changing the
orientation of the protein with respect to the metal surface
is achieved by inserting the His-tag on either side of the
membrane protein surface. Orientational control is mandatory
for experiments in which electrons are injected from the
electrode into the protein. The presented methodology opens
new avenues to study the mechanism of the biomedically
relevant class of electron and voltage-gated proteins on the
atomic level.},
