Electron transfer via domain movement in the cytochrome bc1 complex from Gallus gallus*
References: Zhang, Z.L., Huang, L.S., Shulmeister, V.M., Chi, Y.I., Kim, K.K., Hung, L.W., Crofts, A.R., Berry, E.A., and Kim,… Two conformations of the Rieske ISP are observed in the G. gallus cytochrome bc1, the Qp proximal position and the Qp distal position. Movement of the extrinsic portion of the Rieske ISP between these two positions facilitates electron transfer during ubiquinol oxidation. Prosthetic groups are shown in stick representation beneath a transparent protein surface while the Rieske ISP subunit is shown in the ribbon representation. Subunits are coloured with the Rieske ISP (yellow), cytb6 (green), cytc1 (magenta) and additional peripheral subunits (grey). Prosthetic groups within the complex are coloured with haems c1 (dark blue), b-type haems (bp and bn, red) and the [2Fe-2S] cluster (‘CPK’ colouring with S coloured yellow and Fe coloured red-orange). *PDB IDs: 1BCC, 3BCC.
