molecular function |
| GO:0003824 | | catalytic activity | | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. |
| GO:0004303 | | estradiol 17-beta-dehydrogenase activity | | Catalysis of the reaction: estradiol-17-beta + NADP+ = estrone + NADPH + H+. |
| 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:0047035 | | testosterone dehydrogenase (NAD+) activity | | Catalysis of the reaction: testosterone + NAD+ = androst-4-ene-3,17-dione + NADH. |
biological process |
| GO:0060348 | | bone development | | The process whose specific outcome is the progression of bone over time, from its formation to the mature structure. Bone is the hard skeletal connective tissue consisting of both mineral and cellular components. |
| GO:0071248 | | cellular response to metal ion | | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a metal ion stimulus. |
| GO:0006703 | | estrogen biosynthetic process | | The chemical reactions and pathways resulting in the formation of estrogens, C18 steroid hormones that can stimulate the development of female sexual characteristics. Also found in plants. |
| GO:0008210 | | estrogen metabolic process | | The chemical reactions and pathways involving estrogens, C18 steroid hormones that can stimulate the development of female sexual characteristics. Also found in plants. |
| 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. |
| GO:0055114 | | oxidation-reduction process | | A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons. |
| GO:0006694 | | steroid biosynthetic process | | The chemical reactions and pathways resulting in the formation of steroids, compounds with a 1,2,cyclopentanoperhydrophenanthrene nucleus; includes de novo formation and steroid interconversion by modification. |
| GO:0061370 | | testosterone biosynthetic process | | The chemical reactions and pathways resulting in the formation of testosterone, an androgen having 17beta-hydroxy and 3-oxo groups, together with unsaturation at C-4 C-5. |
cellular component |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| GO:0031965 | | nuclear membrane | | Either of the lipid bilayers that surround the nucleus and form the nuclear envelope; excludes the intermembrane space. |
| GO:0005654 | | nucleoplasm | | That part of the nuclear content other than the chromosomes or the nucleolus. |
