Identification
NamePeptide methionine sulfoxide reductase
Synonyms
  • Peptide-methionine (S)-S-oxide reductase
  • Peptide Met(O) reductase
  • Protein-methionine-S-oxide reductase
Gene NameMXR1
Enzyme Class
Biological Properties
General FunctionInvolved in oxidoreductase activity, acting on a sulfur group of donors, disulfide as acceptor
Specific FunctionHas an important function as a repair enzyme for proteins that have been inactivated by oxidation. Catalyzes the reversible oxidation-reduction of methionine sulfoxide in proteins to methionine. Also able to reduce dimethyl sulfoxide (DMSO) as well, with DMS as the product
