Ferredoxin - NADP+ Reductase
Ferredoxin is a small, iron-containing protein which acts as the electron acceptor associated with Photosystem I in photosynthesis. It accepts an electron and is reduced, giving it the capacity to pass on those electrons as part of the electron transport process. NADP+ reductase catalyzes the reaction in which Ferredoxin is oxidized and NADP+ is reduced to NADPH. NADPH has the energy as a reduced coenzyme to contribute to the Calvin cycle as the primary source of reducing power.
