A	PF08534	Redoxin (Redoxin)	Redoxin	This family of redoxins includes peroxiredoxin, thioredoxin and glutaredoxin proteins.	Domain
B	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
