RA   Hammon N., Israni S., Pitluck S., Di Bartolo G., Trong S., Kellar K.,
RA   Schmutz J., Larimer F., Land M., Ivanova N., Richardson P.;
RT   "Complete sequence of Dechloromonas aromatica RCB.";
RL   Submitted (AUG-2005) to the EMBL/GenBank/DDBJ databases.
CC   -!- CATALYTIC ACTIVITY: Peptide-L-methionine + thioredoxin disulfide +
CC       H(2)O = peptide-L-methionine (R)-S-oxide + thioredoxin.
CC   -!- COFACTOR: Binds 1 zinc ion per subunit. The zinc ion is important
CC       for the structural integrity of the protein (By similarity).
CC   -!- SIMILARITY: Belongs to the msrB Met sulfoxide reductase family.
