Entry
EC 1.8.1.12                 Enzyme                                 
Name
trypanothione-disulfide reductase;
trypanothione reductase;
NADPH2:trypanothione oxidoreductase
Class
Oxidoreductases;
Acting on a sulfur group of donors;
With NAD+ or NADP+ as acceptor
Sysname
trypanothione:NADP+ oxidoreductase
Reaction(IUBMB)
trypanothione + NADP+ = trypanothione disulfide + NADPH + H+ [RN:R03821]
Reaction(KEGG)
R03821;
(other) R08356 R08357
Substrate
trypanothione [CPD:C02090];
NADP+ [CPD:C00006]
Product
trypanothione disulfide [CPD:C03170];
NADPH [CPD:C00005];
H+ [CPD:C00080]
Comment
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)
History
EC 1.8.1.12 created 1989 as EC 1.6.4.8, transferred 2002 to EC 1.8.1.12
