Comments
  • FUNCTION: Has an important function as a repair enzyme for proteins that have been inactivated by oxidation (By similarity). Catalyzes the reversible oxidation-reduction of methionine sulfoxide in proteins to methionine.
  • CATALYTIC ACTIVITY: Peptide-L-methionine + thioredoxin disulfide + H2O = peptide-L-methionine (S)-S-oxide + thioredoxin.
  • CATALYTIC ACTIVITY: L-methionine + thioredoxin disulfide + H2O = L-methionine (S)-S-oxide + thioredoxin.
  • CATALYTIC ACTIVITY: Peptide-L-methionine + thioredoxin disulfide + H2O = peptide-L-methionine (R)-S-oxide + thioredoxin.
  • DOMAIN: Possesses 2 methionine sulfoxide reductase domains (A/MsrA and B/MsrB) and 1 N-terminal thioredoxin domain. The domain B exhibits a thioredoxin dependent methionine sulfoxide reductase activity; the Cys-495 is probably involved in the reduction of MetSO and in formation of the sulfenic acid derivative. The regeneration of Cys-495 is probably done via formation of a disulfide bond with Cys-440 followed by its reduction by thioredoxin.
  • MISCELLANEOUS: The domain msrB is stereospecific for the R isomer of the sulfoxide of MetSO whereas the domain msrA is stereospecific for the S isomer.
  • SIMILARITY: In the N-terminal section; belongs to the thioredoxin family.
  • SIMILARITY: In the central section; belongs to the msrA Met sulfoxide reductase family.
  • SIMILARITY: In the C-terminal section; belongs to the msrB Met sulfoxide reductase family.
  • SIMILARITY: Contains 1 thioredoxin domain.
