Tellurium is a sulphur-like metal. PMID 2157006 Chalogenapyrylium dyes as photochemotherapeutic agents. Cationic selena- and tellurapyrylium dyes were found to inhibit cytochrome c oxidase. PMID 10582332 Ferrochelatase Namely, a [2Fe-2S] cluster is a prosthetic group in mammalian ferrochelatase. PMID 10591529 Role of the Rieske iron-sulphur protein midpoint potential in the protonmotive Q-cycle mechanism of the cytochrome bc1 complex. The midpoint potential of the [2Fe-2S] cluster of the Rieske iron-sulphur protein is the primary determinant of the rate of electron transfer from ubiquinol to cytochrome c catalyzed by the cytochrome bc1 complex.
