Thioredoxin reductase

UniProtKB accession:  Q25861

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the transfer of electrons from NADPH to thioredoxins TRX1, TRX2 and TRX3, which in turn act as reductants of disulfide containing proteins (PubMed:8892299). Able to reduce nitroglutathione (GSNO), a compound involved in the transport of nitric oxide (NO); however, TRX1 is more efficient in reducing GSNO. Has no catalytic activity towards oxidized glutathione (GSSG) (By similarity).
