Effect of H bond removal and changes in the position of the iron–sulphur head domain on the spin–lattice relaxation properties of the [2Fe–2S](2+) Rieske cluster in cytochrome bc(1)

Here, comparative electron spin–lattice relaxation studies of the 2Fe–2S iron–sulphur (Fe–S) cluster embedded in a large membrane protein complex – cytochrome bc(1) – are reported. Structural modifications of the local environment alone (mutations S158A and Y160W removing specific H bonds between Fe...
