Methionine-S-oxide reductase (EC 1.8.4.5, methyl sulfoxide reductase I and II, acetylmethionine sulfoxide reductase, methionine sulfoxide reductase, L-methionine:oxidized-thioredoxin S-oxidoreductase) is an enzyme with systematic name L-methionine:thioredoxin-disulfide S-oxidoreductase.[1][2][3] This enzyme catalyses the following chemical reaction

L-methionine + thioredoxin disulfide + H2O [math]\displaystyle{ \rightleftharpoons }[/math] L-methionine S-oxide + thioredoxin

In the reverse reaction, dithiothreitol can replace reduced thioredoxin.
