EC 1.6.1.4

Accepted name: NAD(P)+ transhydrogenase (ferredoxin)

Reaction: NADH + H+ + 2 NADP+ + 2 reduced ferredoxin [iron-sulfur] cluster = NAD+ + 2 NADPH + 2 oxidized ferredoxin [iron-sulfur] cluster

Other name(s): NADH-dependent reduced ferredoxin:NADP+ oxidoreductase; Nfn; nfnAB (gene names)

Systematic name: NADH:NADP+, ferredoxin oxidoreductase

Comments: The iron-sulfur flavoprotein complex, isolated from the bacterium Clostridium kluyveri, couples the exergonic reduction of NADP+ with reduced ferredoxin and the endergonic reduction of NADP+ with NADH.
