This entry represents the N-terminal domain of thioredoxin 2, which is a zinc finger domain, unusual in thioredoxin proteins [1,2]. Thio2 reduces disulfide bonds and is an efficient electron donor for the essential enzyme ribonucleotide reductase. This domain may mediate protein-protein interactions [1].	Domain
A, B, C, D	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
