Description
Enzyme
Ferredoxin-NADP+ reductase (FRN), also called ferredoxin-NADP+ oxidoreductase, is an enzyme that catalyzes the electron transfer between the electron carrier protein ferredoxin (Fd) and NADP(H).
Ferredoxin-NADP+ reductase is a flavoprotein which can be mainly found in chloroplasts, mitochondria and even bacteria. In plants, this protein is a cellular component that binds to the stromal surface of the thylakoid membrane and which is involved in the last step of the photosynthetic electron transport chain.

Ferredoxin-NADP+ reductase of spinach has two structural domains :
- The first domain, at the N-ter of the protein, is an antiparallel beta barrel that contains the binding site for the FAD cofactor [1].
- The second domain, at the C-ter of the protein, contains an alpha-helix-beta strand fold [1]. This terminal domain is where the NADP+ binds [2].
The interface between these two domains is actually the active site of the ferredoxin-NADP+ reductase.
