OC Bacteria; Firmicutes; Bacillales; Bacillaceae; Bacillus. OX NCBI_TaxID=326423; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RX PubMed=17704766; DOI=10.1038/nbt1325; RA Chen X.H., Koumoutsi A., Scholz R., Eisenreich A., Schneider K., RA Heinemeyer I., Morgenstern B., Voss B., Hess W.R., Reva O., Junge H., RA Voigt B., Jungblut P.R., Vater J., Suessmuth R., Liesegang H., RA Strittmatter A., Gottschalk G., Borriss R.; RT "Comparative analysis of the complete genome sequence of the plant RT growth-promoting bacterium Bacillus amyloliquefaciens FZB42."; RL Nat. Biotechnol. 25:1007-1014(2007). 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.
