== Function ==
[https://www.uniprot.org/uniprot/THIO1_PLAF7 THIO1_PLAF7] Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions (PubMed:11013257, PubMed:20673832). By modifying the redox status of targeted proteins, induces changes in their structure and activity (PubMed:19360125, PubMed:20673832). Reduces oxidized glutathione (GSSG), thereby acting as a backup for the glutathione redox system (PubMed:11013257). Reduces nitroglutathione (GSNO), a compound involved in the transport of nitric oxide (NO) (PubMed:11013257). Also reduces oxidative stress by detoxifying hydrogen peroxide, tert-butyl hydroperoxide and cumene hydroperoxide (PubMed:14962358). Activates ornithine aminotransferase OAT by reducing a disulfide bond in the substrate binding loop, thereby enhancing the affinity of OAT for its substrates (PubMed:20673832). May reduce S-adenosyl-L-homocysteine hydrolase SAHH (PubMed:19360125).<ref>PMID:11013257</ref> <ref>PMID:14962358</ref> <ref>PMID:19360125</ref> <ref>PMID:20673832</ref>
