Lubitz, Reijerse & Messinger have published a fascinating review into the intricacies of photosystem II and hydrogenases that produce hydrogen – Note the marvels within Darwn’s blob of “protoplasm”. It is most interesting that Lubitz et al. address the design principles that we can learn from “nature” and apply to creating synthetic photochemical biosynthetic water splitting systems.Though attributed to “nature”, recognizing design principles and applying them are easily understood at the Max Planck Institut für Bioanorganische Chemie. I wonder when No. America will catch up? From the very detailed complexity described, I highly expect some “irreducibly complex” systems are present. Any candidates? Following are a few extracts from this excellent review.

This review aims at presenting the principles of water-oxidation in photosystem II and of hydrogen production by the two major classes of hydrogenases in order to facilitate application for the design of artificial catalysts for solar fuel production. . . .
. . .A promising way for light-driven water splitting would be to mimic the molecular and supramolecular organization of the natural photosynthetic system, i.e.
artificial photosynthesis
