Peptide-methionine (S)-S-oxide reductase (EC 1.8.4.11, MsrA, methionine sulphoxide reductase A, methionine S-oxide reductase (S-form oxidizing), methionine sulfoxide reductase A, peptide methionine sulfoxide reductase, formerly protein-methionine-S-oxide reductase) is an enzyme with systematic name peptide-L-methionine:thioredoxin-disulfide S-oxidoreductase (L-methionine (S)-S-oxide-forming). [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] This enzyme catalyses the following chemical reaction
- (1) peptide-L-methionine + thioredoxin disulfide + H2O peptide-L-methionine (S)-S-oxide + thioredoxin
- (2) L-methionine + thioredoxin disulfide + H2O L-methionine (S)-S-oxide + thioredoxin
The reaction occurs in the reverse direction.
