abstract = {To establish a semiartificial device for (bio-)hydrogen
production utilizing photosynthetic water oxidation, we
report on the immobilization of a Photosystem 2 on electrode
surfaces. For this purpose, an isolated Photosystem 2 with a
genetically introduced His tag from the cyanobacterium
Thermosynechococcus elongatus was attached onto gold
electrodes modified with thiolates bearing terminal
Ni(II)-nitrilotriacetic acid groups. Surface enhanced
infrared absorption spectroscopy showed the binding kinetics
of Photosystem 2, whereas surface plasmon resonance
measurements allowed the amount of protein adsorbed to be
quantified. On the basis of these data, the surface coverage
was calculated to be 0.29 pmol protein cm(-2), which is in
agreement with the formation of a monomolecular film on the
electrode surface. Upon illumination, the generation of a
photocurrent was observed with current densities of up to 14
microA cm(-2) . This photocurrent is clearly dependent on
light quality showing an action spectrum similar to an
isolated Photosystem 2. The achieved current densities are
equivalent to the highest reported oxygen evolution
activities in solution under comparable conditions.},
