molecular function |
| GO:0051537 | | 2 iron, 2 sulfur cluster binding | | Interacting selectively and non-covalently with a 2 iron, 2 sulfur (2Fe-2S) cluster; this cluster consists of two iron atoms, with two inorganic sulfur atoms found between the irons and acting as bridging ligands. |
| GO:0036200 | | 3-ketosteroid 9-alpha-monooxygenase activity | | Catalysis of the reaction: androsta-1,4-diene-3,17-dione + NADH + H+ + O2 = 9alpha-hydroxyandrosta-1,4-diene-3,17-dione + NAD+ + H2O. |
| GO:0008198 | | ferrous iron binding | | Interacting selectively and non-covalently with ferrous iron, Fe(II). |
| GO:0005506 | | iron ion binding | | Interacting selectively and non-covalently with iron (Fe) ions. |
| GO:0051536 | | iron-sulfur cluster binding | | Interacting selectively and non-covalently with an iron-sulfur cluster, a combination of iron and sulfur atoms. |
| GO:0047086 | | ketosteroid monooxygenase activity | | Catalysis of the reaction: O2 + NADPH + progesterone = H2O + NADP+ + testosterone acetate. |
| GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| GO:0016491 | | oxidoreductase activity | | Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. |
| GO:0050292 | | steroid 9-alpha-monooxygenase activity | | Catalysis of the reaction: AH(2) + O(2) + pregna-4,9(11)-diene-3,20-dione = 9,11alpha-epoxypregn-4-ene-3,20-dione + A + H(2)O. |
biological process |
| GO:0006707 | | cholesterol catabolic process | | The chemical reactions and pathways resulting in the breakdown of cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones. |
| GO:0016042 | | lipid catabolic process | | The chemical reactions and pathways resulting in the breakdown of lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. |
| GO:0006629 | | lipid metabolic process | | The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids. |
