Wiring an [FeFe]-Hydrogenase with Photosystem I for Light-Induced Hydrogen Production

<br/><br/> A molecular wire is used to connect two proteins through their physiologically relevant redox cofactors to facilitate direct electron transfer. Photosystem I (PS I)and an [FeFe]-hydrogenase (H2ase)serve as the test bed for this new technology. By tethering a photosensitizer with a hydrogen-evolving catalyst, attached by Fe-S coordination bonds between the FB iron-sulfur cluster of PS I and the distal iron-sulfur cluster of H2ase, we assayed electron transfer between the two components via light-induced hydrogen generation. These hydrogen-producing nanoconstructs self-assemble when the PS I variant, the H2ase variant, and the molecular wire are combined.
