Conformational changes in the chlorophyll phytyl tail control access to and from the plastoquinol oxidation (Qp) site in cytochrome b6f*
Malone, L.A., Qian, P., Mayneord, G.E., Hitchcock, A., Farmer, D.A., Thompson, R.F., Swainsbury, D.J.K., Ranson, N.A., Hunter, … The two conformations of the chlorophyll tail resolved in the cytochrome b6f structure from spinach control access of substrate to and from the Qp pocket. Subunits are coloured with the Rieske ISP (yellow), cytb6 (green), subunit IV (cyan) and cytf (magenta). The Chl a molecule is coloured green and shown in stick representation beneath a semi-transparent protein surface (*PDB ID: 6RQF).
