I have isolated and characterized three enzymes that are essential for the biosynthesis of all steroid hormones in all steroidogenic tissues:
| Enzyme Name | Abbr. | Enzyme code | Gene |
|---|---|---|---|
| Cholesterol side-chain-cleaving cytochrome P450scc | P450scc | EC 1.14.15.6 | CYP11A |
| Cytochrome P45011β monooxygenase | P450c11 | EC 1.14.15.4 | CYP11B1 |
| Adrenodoxin reductase | EC 1.18.1.6 | FDXR |
