ID 1.18.1.6 DE adrenodoxin-NADP(+) reductase. AN adrenodoxin reductase. AN nicotinamide adenine dinucleotide phosphate-adrenodoxin reductase. CA H(+) + NADP(+) + 2 reduced [adrenodoxin] = NADPH + 2 oxidized CA [adrenodoxin]. CC -!- The enzyme, which transfers electrons from NADPH to adrenodoxin CC molecules, is the first component in the mitochondrial cytochrome CC P450 electron transfer systems, and is involved in the biosynthesis CC of all steroid hormones.
