WebDec 15, 1986 · Ferredoxin: NADP+ reductase has a molecular weight of 35300 (2) with a single FAD at the active site. It is associated, with the stromal side of the thylakoid membrane (3) although it is readily solubilised and most physicochemical studies have been carried out with the free enzyme. WebFerredoxin-NADP+ reductase (FNR) is the common name of members of a broad group of flavoenzymes (classified as EC 1.18.1.2) sharing the ability to catalyze the transfer of reducing equivalents between NADP (H) and ferredoxins (Fds).
WebAfter being energized at photosystem I/P700, the electrons are transferred to the electron carrier molecule, ferredoxin, and then to the enzyme, ferredoxin-NADP+ reductase. This enzyme reduces NADP+ to form NADPH + H in the stroma. Alternatively, the energized electrons can undergo cyclic photophosphorylation, where they are transferred back to ...
