As deduced from its gene structure in E. coli, cytochrome b03 is strongly related to the superfamily of heme-copper containing enzymes. In particular, the enzyme catalyzes the two-electron oxidation of ubiquinol and the four-electron reduction of O2 to H20 and it couples the free energy of these electron-transfer processes to translocate protons on the periplasmic side of the membrane. Cytochrome b03 contains a six-coordinated, low-spin b-type heme; a five-coordinated, high-spin oxygen-binding otype heme; and one copper atom (CUB). The heme 0 is structurally related to heme a with a methyl residue replacing the formyl group at pyrrole ring D [1] | URI: | https://hdl.handle.net/20.500.14279/1093 | ISSN: | 14763516 | DOI: | 10.1155/1999/24629 | Rights: | © Hindawi Publishing Corporation | Type: | Article | Affiliation: | University of Crete | Affiliation: | University of Crete Michigan State University University of Helsinki |
