RX PubMed=15213324; DOI=10.1073/pnas.0402521101; RA Holden M.T.G., Feil E.J., Lindsay J.A., Peacock S.J., Day N.P.J., RA Enright M.C., Foster T.J., Moore C.E., Hurst L., Atkin R., Barron A., RA Bason N., Bentley S.D., Chillingworth C., Chillingworth T., RA Churcher C., Clark L., Corton C., Cronin A., Doggett J., Dowd L., RA Feltwell T., Hance Z., Harris B., Hauser H., Holroyd S., Jagels K., RA James K.D., Lennard N., Line A., Mayes R., Moule S., Mungall K., RA Ormond D., Quail M.A., Rabbinowitsch E., Rutherford K.M., Sanders M., RA Sharp S., Simmonds M., Stevens K., Whitehead S., Barrell B.G., RA Spratt B.G., Parkhill J.; RT "Complete genomes of two clinical Staphylococcus aureus strains: RT evidence for the rapid evolution of virulence and drug resistance."; RL Proc. Natl. Acad. Sci. U.S.A. 101:9786-9791(2004). CC -!- FUNCTION: Has an important function as a repair enzyme for CC proteins that have been inactivated by oxidation. Catalyzes the CC reversible oxidation-reduction of methionine sulfoxide in proteins CC to methionine (By similarity). CC -!- CATALYTIC ACTIVITY: Peptide-L-methionine + thioredoxin disulfide + CC H(2)O = peptide-L-methionine (S)-S-oxide + thioredoxin. CC -!- CATALYTIC ACTIVITY: L-methionine + thioredoxin disulfide + H(2)O = CC L-methionine (S)-S-oxide + thioredoxin. CC -!- SIMILARITY: Belongs to the msrA Met sulfoxide reductase family.
