Photosystem I.
based on mapping to UniProt P05311
Reduced plastocyanin + oxidized ferredoxin + light = oxidized plastocyanin + reduced ferredoxin.
-!- Contains chlorophyll, phylloquinones, carotenoids and [4Fe-4S] clusters. -!- Cytochrome c6 can act as an alternative electron donor, and flavodoxin as an alternative acceptor in some species.
