1.8.4.14 | L-methionine (R)-S-oxide + thioredoxin |
fRMsr exhibits the highest Met-(R)-O reductase activity when all components of the NADPHTrxR-Trx system are present in the reaction. The enzyme is not able to reduce L-methionine (S)-S-oxide, Met sulfone, dimethyl sulfoxide, or MetO when present in the synthetic peptide NH2-Pro-Thr-Ser-Met-(RS)-O-Glu-His-Val-NH2. Escherichia coli fRMsr is the first GAF domain family member to show enzymatic activity |
