| Other name(s): |
fRMsr; FRMsr; free met-R-(o) reductase; free-methionine (R)-S-oxide reductase |
| Systematic name: |
L-methionine:thioredoxin-disulfide S-oxidoreductase [L-methionine (R)-S-oxide-forming] |
| Comments: |
Requires NADPH. Unlike EC 1.8.4.12, peptide-methionine (R)-S-oxide reductase, this enzyme cannot use peptide-bound methionine (R)-S-oxide as a substrate [1]. Differs from EC 1.8.4.13, L-methionine (S)-S-oxide in that L-methionine (S)-S-oxide is not a substrate. |
