The cytochrome b6f complex (plastoquinol—plastocyanin reductase; EC 1.10.99.1) is an enzyme found in the thylakoid membrane in chloroplasts of plants, cyanobacteria, and green algae, catalyzing the transfer of electrons from plastoquinol to plastocyanin. Ferredoxin-plastoquinone reductase (FQR) activity during cyclic electron flow (CEF) was first ascribed to the cytochrome b 6 f complex ( b 6 f ). The reaction was inhibited by about 60% in the presence of 2 µM 2-n-nonyl-4-hydroxyquinoline N-oxide, an inhibitor of the cytochrome b₆ f complex at the Q(i) site, while it was not affected by triphenyltin or isobutyl cyanide that interacts with the recently identified heme c(i) . iron sulfur proteins that mediate electron transfer, last electron acceptor and reduces NADPH reductase or transfers them to enzyme ferredoxin NADP+ oxidoreductase. and shown to be very similar both to the global fold in soln.

The obtained data indicate that FNR associated with the cytochrome b₆ f complex can participate in the cyclic electron transport as PSI-PQ or NADPH-PQ oxidoreductase. 72 • The electrons from cytochrome b 6 f are passed to another mobile electron carrier, a water-soluble, copper-containing, peripheral membrane protein called plastocyanin, situated on the luminal side of the thylakoid membrane • Plastocyanin carries electrons to the luminal side of PSI, where they are transferred to P700 +, the positively charged reaction-center pigment of PSI.
