High-resolution structure of monomeric photosystem I from Thermosynechococcus vestitus
Photosystem I (PSI) exists in trimeric (tPSI) and monomeric (mPSI) forms within the thylakoid membrane of cyanobacteria. PSI functions as a light-driven electron pump, enabling the transfer of electrons from cytochrome c6 (Cyt c6) or plastocyanin to ferredoxin. Here, we have developed a novel protocol to obtain large a...
