Engineering Of Photosystem I Attachment To Titanium Oxide Nanostructures Via Ferredoxin-Fusion Proteins, Tuo Zhu

Masters Theses

Ferredoxins (Fds) are iron-sulfur proteins that mediate electron transfer in a range of metabolic reactions. In the thylakoid membrane of photosynthetic organisms, Fd facilitates electron transfer from the stromal surface of photosystem I (PSI) to the ferredoxin Nicotinamide adenine dinucleotide phosphate oxidoreductase (FNR), which requires that Fd is capable of docking and transferring electrons between these two complexes. In applied photosynthesis, many efforts have been devoted towards re-directing these electrons into either a hydrogen-evolving catalyst or an electron-conducting semiconductor. In this study, the electrons from the PSI complex are directed to a titanium oxide (TiO₂) electrode, and Fd …
