Abstract
⺠Crystal structures of cyt bc1 complexes have been determined from diverse organisms. ⺠ISP-ED, the extrinsic domain of iron-sulfur protein, undergoes binary conformational changes upon binding of different inhibitors. ⺠ISP-ED conformation is controlled through modulating its binding affinity to cyt b subunit. ⺠Bifurcated ET can be explained by the “surface-affinity modulated ISP motion switch hypothesis”. ⺠This mechanism has received substantial experimental support.
