NADH-dependent reduced ferredoxin:NADP+ oxidoreductase;
Nfn;
nfnAB (gene names)
Class
Oxidoreductases;
Acting on NADH or NADPH;
With NAD+ or NADP+ as acceptor
BRITE hierarchy
Sysname
NADH:NADP+, ferredoxin oxidoreductase
Reaction(IUBMB)
NADH + H+ + 2 NADP+ + 2 reduced ferredoxin [iron-sulfur] cluster = NAD+ + 2 NADPH + 2 oxidized ferredoxin [iron-sulfur] cluster
Substrate
NADH [CPD:C00004];
H+ [CPD:C00080];
NADP+ [CPD:C00006];
reduced ferredoxin [iron-sulfur] cluster [CPD:C00138]
Product
NAD+ [CPD:C00003];
NADPH [CPD:C00005];
oxidized ferredoxin [iron-sulfur] cluster [CPD:C00139]
Comment
The iron-sulfur flavoprotein complex, originally isolated from the bacterium Clostridium kluyveri, couples the exergonic reduction of NADP+ with reduced ferredoxin and the endergonic reduction of NADP+ with NADH.
