Protein attributes

Sequence length	309 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Has 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 By similarity.
Catalytic activity	Peptide-L-methionine + thioredoxin disulfide + H(2)O = peptide-L-methionine (S)-S-oxide + thioredoxin. L-methionine + thioredoxin disulfide + H(2)O = L-methionine (S)-S-oxide + thioredoxin. Peptide-L-methionine + thioredoxin disulfide + H(2)O = peptide-L-methionine (R)-S-oxide + thioredoxin.
Sequence similarities	In the N-terminal section; belongs to the msrA Met sulfoxide reductase family. In the C-terminal section; belongs to the msrB Met sulfoxide reductase family.
