Heme-thiolate

WebOne of the more intriguing aspects of cytochrome P450 is the enzyme's use of a thiolate-ligated heme to perform demanding two-electron oxidations. This coordination is unusual, given that thiolate ligation can significantly decrease a heme reduction potential. Web7 apr. 2009 · X-ray crystallographic analysis confirms that replacing the heme–thiolate with a heme–selenolate constitutes a highly conservative substitution. Despite the slightly larger van der Waals radius of selenium compared with sulfur, the geometry and environment of the heme ligand are fully preserved in the mutant.
