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. HAMAP MF_01400

Catalytic activity

Peptide-L-methionine + thioredoxin disulfide + H2O = peptide-L-methionine (S)-S-oxide + thioredoxin. HAMAP MF_01400

L-methionine + thioredoxin disulfide + H2O = L-methionine (S)-S-oxide + thioredoxin. HAMAP MF_01400

Peptide-L-methionine + thioredoxin disulfide + H2O = 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.
