Cytochrome f (Cytf) is the largest subunit of the cytochrome b6f complex. This complex transfers electrons from plastocyanin to the two reaction center complexes of oxygenic photosynthetic membranes.[1]

See also Hemeproteins.

Structural highlights

The cytochrome b6f complex contains 4 subunits: 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.

(PDB entry 1ctm).
