Abstract

A change for the better: The proximal cysteine thiolate in a cytochrome P450 enzyme is replaced by a selenocysteine. The resulting selenolate-ligated CYP119 protein has UV/Vis (see spectrum, ), EPR, and resonance Raman spectra that are similar to those of the native protein ( - ). These results are the first to fully describe a hemoprotein with a selenolate proximal ligand.
