Flavoprotein pyridine nucleotide cytochrome reductases catalyse the interchange of reducing equivalents between one-electron carriers and the two-electron-carrying nicotinamide dinucleotides. The enzymes include ferredoxin-NADP+ reductases plant and fungal NAD(P)H:nitrate reductases cytochrome b5 reductases cytochrome P450 reductases sulphite reductases nitric oxide synthases phthalate dioxygenase reductase and various other flavoproteins.
