| Accepted name: |
photosystem I |
| Reaction: |
reduced plastocyanin + oxidized ferredoxin + hν = oxidized plastocyanin + reduced ferredoxin |
| Systematic name: |
plastocyanin:ferredoxin oxidoreductase (light-dependent) |
| Comments: |
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. |
