C [auth A], D [auth B], E [auth C], F [auth D]	PF01625	Peptide methionine sulfoxide reductase (PMSR)	Peptide methionine sulfoxide reductase	This enzyme repairs damaged proteins. Methionine sulfoxide in proteins is reduced to methionine.	Domain
A [auth E], B [auth F], G	PF00085	Thioredoxin (Thioredoxin)	Thioredoxin	Thioredoxins are small enzymes that participate in redox reactions, via the reversible oxidation of an active centre disulfide bond. Some members with only the active site are not separated from the noise.	Domain
