How oxygen attacks [FeFe] hydrogenases from photosynthetic organisms.

TL;DR: X-ray absorption spectroscopy shows that reaction with oxygen results in destruction of the [4Fe-4S] domain of the active site H-cluster while leaving the di-iron domain (2FeH) essentially intact, suggesting that a very high level of discrimination can be achieved by subtle factors such as electronic effects (specific orbital overlap requirements) and steric constraints at theactive site.

Electrochemical kinetic investigations of the reactions of [FeFe]-hydrogenases with carbon monoxide and oxygen: comparing the importance of gas tunnels and active-site electronic/redox effects.

TL;DR: A major obstacle for future biohydrogen production is the oxygen sensitivity of [FeFe]-hydrogenases, the highly active catalysts produced by bacteria and green algae, and the model proposed shows the most sluggish gas transport and hence little dependence of inactivation rate on H-cluster state, whereas DdHydAB shows a large dependence on H/O(2) state and the least effective barrier to gas transport.

Surface-enhanced infrared absorption spectroscopy (SEIRAS) to probe monolayers of membrane proteins.
TL;DR: It is demonstrated that the interpretations of all of these experiments critically depend on the orientation of the solid-supported membrane protein, and future directions of SEIRAS including cellular systems are discussed.

How algae produce hydrogen--news from the photosynthetic hydrogenase.
Sven T. Stripp,Thomas Happe +1 more
TL;DR: This review traces the discovery of this interesting class of proteins, with emphasis on novel discoveries of the hydrogenase interaction with its natural electron donor ferredoxin and the mechanism of enzyme inactivation through oxygen.

[FeFe]-Hydrogenases: recent developments and future perspectives
TL;DR: The essential findings regarding the redox chemistry of [FeFe]-hydrogenases are summarized and their catalytic hydrogen turnover is discussed and an outlook on potential research activities and the utilization of synthetic cofactor mimics is given.
