Abstract:
We prepared ATP photosynthetic vesicles from inside-out membranes of Escherichia coli cells that express delta-rhodopsin (a novel light-driven H(+) transporter) and TF(0)F(1)-ATP synthase (a thermo-stable ATP synthase). These vesicles showed light-dependent ATP synthesis. Furthermore, coupling the ATP photosynthetic vesicles with an ATP-hydrolyzing hexokinase enabled light-dependent glucose consumption. The ATP photosynthetic vesicles indicate their potential to applied to light-driven ATP-regenerating bioprocess for various ATP-hydrolyzing bioproductions.

Photosystem I
Both these photosystems work in concert. An excited electron from PSII is relayed to PSI via an electron transport chain in the thylakoid membrane of the chloroplast, which is comprised of the carrier molecule plastoquinone, the dual-protein cytochrome complex, and plastocyanin. As electrons move between PSII and PSI, they lose energy and must be re-energized...
