Other names:
NADPH2:trypanothione oxidoreductase
trypanothione reductase
NADPH:trypanothione oxidoreductase
N1,N8-bis(glutathionyl)spermidine reductase

Reaction

Cofactor

Comments:

Trypanothione disulfide is the oxidized form of N1,N8-bis(glutathionyl)-spermidine from the insect-parasitic trypanosomatid Crithidia fasciculata. The enzyme from Crithidia fasciculata is a flavoprotein (FAD), whose activity is dependent on a redox-active cystine at the active centre (cf. EC 1.8.1.7, glutathione-disulfide reductase).
