Cysteine-125 is the catalytic residue of Saccharomyces cerevisiae free methionine-R-sulfoxide reductase.

Biochemical and biophysical research communications - 7 May 2010

Abstract excerpt

Free methionine-R-sulfoxide reductase (fRMsr) is a new type of methionine sulfoxide reductase that catalyzes the reduction of free methionine-R-sulfoxide to methionine. This enzyme cannot reduce oxidized methionine residues in proteins. While three Cys residues, Cys-91, Cys-101 and Cys-125, have been demonstrated to be involved in the catalysis by Saccharomyces cerevisiae fRMsr, their specific functions have not...
