The Rieske protein of the ubiquinol-cytochrome c oxidoreductase (bc1 complex or b6f complex) contains a [2Fe-2S] cluster which is thought to be bound to the protein via two nitrogen and two sulfur ligands [Britt, R. D., Sauer, K., Klein, M. P., Knaff, D. B., Kriauciunas, A., Yu, C.-A., Yu, L., & Malkin, R. (1991) Biochemistry 30, 1892-1901; Gurbiel, R. J.,(More)
The nonphotosynthetic mutant R126 of Rhodobacter capsulatus has a cytochrome (cyt) bc1 complex (EC 1.10.2.2) with a defective quinol oxidation Qz(o,p) site but a functional quinone reduction Qc(i,n) site. Genetic analyses of this mutant have indicated that a single-base-pair change has replaced Gly-158 of cyt b with Asp. In this work, Gly-158 was changed by(More)
