WebA key role of the thylakoid membranes in chloroplasts is the generation of a proton electrochemical gradient. This is achieved in two ways. The first is through the sequential action of Photosystem II, which splits water and releases oxygen, the cytochrome b6f complex, and Photosystem I.

WebEach monomeric complex is composed of four large subunits [cytochrome b6, subunit IV, cytochrome f, and the Rieske iron sulfur protein (ISP)] and four small subunits (PetG, PetL, PetM, and PetN). Three of the large subunits (cytochrome b6, cytochrome f, and the Rieske ISP) bind redox-active prosthetic groups.
