'''Cytochrome f''' (Cytf) is the largest subunit of the cytochrome b6f complex. This complex transfers electrons between the two reaction center complexes of oxygenic photosynthetic membranes. The cytochrome b6f complex contains 4 Cytf, Cytb6, Rieske iron-sulfur protein and subunit IV. Cytf has an internal chain of water molecules conserved in all its 3D structures. The water chain is assumed to be a proton wire.
