Fotosistem I (EC 1.97.1.12, Photosystem I) je enzim sa sistematskim imenom plastocijanin:feredoksin oksidoreduktaza (zavisna od svetla).[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju
- redukovani plastocijanin + oksidovani feredoksin + hnu oksidovani plastocijanin + redukovani feredoksin
Ovaj enzim sadrži hlorofil, filohinone, karotenoide i [4Fe-4S] klustere. Citohrom c6 može da deluje kao alternativni elektronski donor.
