Flavoprotein pyridine nucleotide cytochrome reductases

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.
