Title: Cell-Free Synthetic Biology Chassis for Nanocatalytic Photon-to-Hydrogen Conversion

Abstract

We report on entirely man-made nanobio hybrid fabricated through assembly of cell-free expressed transmembrane proton pump and semiconductor nanoparticles as an efficient nanocatalysis for photocatalytic H 2 evolution. The system produces H 2 at a turnover rate of 239 (μmole protein) -1 h -1 under green and 17742 (μmole protein) -1 h -1 under white light at ambient conditions, in water at neutral pH with methanol as a sacrificial electron donor. Robustness and flexibility of this approach allows for systemic manipulation at nanoparticle-bio interface toward directed evolution of energy transformation materials and artificial systems.
