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_01401

Catalytic activity

L-methionine + thioredoxin disulfide + H2O = L-methionine (S)-S-oxide + thioredoxin. HAMAP MF_01401 SAAS SAAS002569

Peptide-L-methionine + thioredoxin disulfide + H2O = peptide-L-methionine (S)-S-oxide + thioredoxin. HAMAP MF_01401 SAAS SAAS002569

Sequence similarities

Belongs to the MsrA Met sulfoxide reductase family. HAMAP MF_01401
