Protein of Rieske

The Protein iron-sulfur, composing of the complex cytochrome '' bc '' 1 was discovered and insulated by John S. Rieske and coll in 1964. The counterparts of the Protéine S of Rieske include/understand components " protein iron-soufre" cytochrome '' B '' 6 '' F '' complex), Dioxygénases hydroxylant the aromatic cycles (phthalate dioxygénase, Benzene, napthalene and toluene 1,2-dioxygénases) and the arsenite oxydase (N° EC. 1.20.98.1).

Cys-Xaa-His- (Xaa) 15-17-Cys-Xaa-Xaa-His

The hook structures off has off number Rieske proteins are known. The overall fold, comprising two subdomains, is dominated by antiparallel β-structure and contains the only α-helix. The smaller " cluster-binding" subdomains in mitochondrial and chloroplast proteins are virtually identical, whereas the broad subdomains different are substantially in splashes off has common folding camera topology. The cluster-binding subdomains cuts the topology off year incomplete antiparallel β-barrel. One iron atom off the Rieske cluster is coordinated by two Cystein residues and the other is coordinated by two Histidine residues through the Nδ atoms. The ligands coordinating the cluster originate from two loops; each loop contributes one Cys and one His. -->
