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