RA   Copeland A., Lucas S., Lapidus A., Barry K., Detter J.C., Glavina T.,
RA   Hammon N., Israni S., Pitluck S., Saunders E.H., Schmutz J.,
RA   Larimer F., Land M., Kyripides N., Anderson I., Richardson P.;
RT   "Complete sequence of Pseudomonas fluorescens PfO-1.";
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.
