Photosystem I iron-sulfur center

Gene:

psaC Enzyme: EC 1.97.1.12 This enzyme has known catalytic activity involved in reaction: reduced [plastocyanin] + hnu + oxidized [2Fe-2S]-[ferredoxin] = oxidized [plastocyanin] + reduced [2Fe-2S]-[ferredoxin]

Organism:

Cyanidioschyzon merolae (strain NIES-3377 / 10D) (Unicellular red alga)

Uniprot:

Q85G47go to UniProt

Biological function:

Apoprotein for the two 4Fe-4S centers FA and FB of photosystem I (PSI); essential for photochemical activity. FB is the terminal electron acceptor of PSI, donating electrons to ferredoxin. The C-terminus interacts with PsaA/B/D and helps assemble the protein into the PSI complex. Required for binding of PsaD and PsaE to PSI. PSI is a plastocyanin/cytochrome c6-ferredoxin oxidoreductase, converting photonic ... [show more]go to UniProt
