Cytochrome f

spinqualitylabelsall models Turnip heme-containing cytochrome f (PDB entry 1ctm) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D 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. 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. Heme binding site in Turnip cytochrome f Covalent binding of heme to 2 Cys residues Fe coordination site (PDB entry 1ctm).
