The 3 substrates of this enzyme are reduced ferredoxin, NADP+, and H+, whereas its two products are oxidized ferredoxin and NADPH. It has a flavin cofactor, FAD.
This enzyme belongs to the family of oxidoreductases, that use iron-sulfur proteins as electron donors and NAD+ or NADP+ as electron acceptors.
This enzyme participates in photosynthesis. FNR provides a major source of NADPH for photosynthetic organisms.[1]
