WebOct 1, 2024 · The identity of the cystine reductase(s) that consume NADPH to reduce cystine to cysteine still remains elusive. Previous studies implicated that thioredoxin-related protein of 14 kDa (TRP14) and thioredoxin reductase 1 (Txnrd1) are potential cystine reductases (Mandal et al., 2010; Pader et al., 2014). Both TRP14 and Txnrd1 are indeed … WebMay 1, 2024 · The cell obtains its cysteine via import of cystine (the oxidized dimer form of cysteine) from the extracellular environment via a cystine/glutamate antiporter dubbed system xC-/xCT. Imported cystine is then reduced via cystine reductase and used by two enzymes, glutamate-cysteine ligase (GCL) (previously known as gamma glutamyl …

WebThe E. intestinalis enzyme (EiAPR) is composed of a reductase domain and a glutaredoxin-like C-terminal domain. The enzyme contains a single [4Fe-4S] cluster as its sole prosthetic group. Three of the enzyme's eight cysteine residues (Cys166, Cys257, and Cys260) serve as ligands to the iron−sulfur cluster. Webreductase that can catalyze S-denitrosylation reactions. Results TRP14 Is an Efficient L-Cystine Reductase. Like Trx1, TRP14 was earlier shown to be a ubiquitously expressed cytosolic protein (5). Using estimates from immunoblots with recombinant pro-tein standards, we first compared the expression of TRP14 and Trx1 in different cell lines.
