Transports electrons between flavodoxin or ferredoxin and NADPH. H(+) + NADP(+) + 2 reduced [2Fe-2S]-[ferredoxin] = NADPH + 2 oxidized [2Fe-2S]-[ferredoxin] NADP(+) + reduced [flavodoxin] = 2 H(+) + NADPH + oxidized [flavodoxin] kcat is 222 sec(-1) with K(3)Fe(CN)(6) as substrate. kcat is 20 sec(-1) with 2,6-dichlorophenolindophenol as substrate. Monomer. Induced under oxidative stress conditions. Belongs to the ferredoxin--NADP reductase type 1 family. Extended N-terminus.
