A	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

The domain is thioredoxin-like, hence referred to as Trx1 ...	This domain is found in Quiescin sulfhydryl oxidase (QSOX), an oxidoreductase present in Homo sapiens capable of both generating and transferring disulfide modules within a single polypeptide. The domain is thioredoxin-like, hence referred to as Trx1 domain. Trx1 domain has a di-cysteine motif (Cys-X-X-Cys) which is related to the redox-active domains of protein disulfide isomerase. The Trx1 domain is responsible for intramolecular disulfide transfer through the di-cysteine motif [1].	Domain
