Author A Holmgren 1 Affiliation 1 Department of Physiological Chemistry, … WebStudies show that the glutaredoxin system with glutathione plays a backup role to keep oxidized thioredoxin 1 (Trx1) reduced in cells with loss of thioredoxin reductase 1 (TrxR1) activity. Data show that glutaredoxin acts as a reductant for methionine sulfoxide reductases A and B (MsrA and MsrB) with or without resolving cysteine.
