| steroid 21-monooxygenase | <enzyme> A steroid hydroxylase system found in adrenal cortex microsomes. It catalyses the 21-hydroxylation of corticosteroids and shows a requirement for NADPH and molecular oxygen. Its deficiency is a cause of adrenogenital syndrome. Chemical name: Steroid,hydrogen-donor:oxygen oxidoreductase (21-hydroxylating) Registry number: EC 1.14.99.10 (12 Dec 1998) |
|---|---|
| steroid (23R)-hydroxylase | <enzyme> Increased (23r)-hydroxylase activity in patients with cerebrotendinous xanthomatosis, an inborn error of metabolism in bile acid synthesis resulting in (23r)-hydroxylation of bile acids Registry number: EC 1.14.99.- Synonym: bile acid (23r)-hydroxylase, bile alcohol (23r)-hydroxylase (26 Jun 1999) |
| steroid 25-hydroxylase | <enzyme> Involved in cholesterol degradation to cholic acid Registry number: EC 1.14.99.- (26 Jun 1999) |
| steroid 5a-reductase | <enzyme> An enzyme that uses NADPH to reduce certain steroids (e.g., the conversion of testosterone to dihydrotestosterone a deficiency of this enzyme is associated with a form of male pseudohermaphroditism in which genetic males have male genitals as well as female external genitalia. (05 Mar 2000) |
| steroid 7 alpha-hydroxylase | <enzyme> Testosterone and androstenedione incubated with microsomes from rat testes produced 7alpha-hydroxytestosterone and 7alpha-hydroxyandrostenedione Registry number: EC 1.14.99.- Synonym: testicular 7 alpha-hydroxylase, 7 alpha-hydroxylase, microsomal 7alpha-hydroxylase, andiostenedione 7 alpha-hydroxylase, sterol 7 alpha-hydroxylase, cytochrome p-450iia1, cytochrome p450iia1 (26 Jun 1999) |
| steroid 9 alpha monooxygenase | <enzyme> Consists of an electron transport chain of NADH-dependent flavoprotein reductase and 2 iron-sulfur proteins; from nocardia Registry number: EC 1.14.99.- Synonym: steroid 9 alpha-hydroxylase (26 Jun 1999) |
| steroid acne | Folliculitis similar to acne vulgaris, but resulting from topical or oral administration of steroids; comedones are rare. (05 Mar 2000) |
| steroid alpha-ketol oxidase | <enzyme> In conjunction with corticosteroid side-chain-isomerase (EC 5.3.1.21) converts desoxycorticosterone to a 20-oxo-21-oic acid (pregnenoic acid) Registry number: EC 1.2.1.- (26 Jun 1999) |
| steroid delta-isomerase | <enzyme> Pharmacological action: enzyme inhibitor Registry number: EC 5.3.3.1 Synonym: delta 5-3-oxosteroid isomerase, delta-5-3-ketosteroid isomerase, 3-ketosteroid isomerase, 3-oxosteroid delta 4-5 isomerase, 5-ene-3-ketosteroid isomerase, 5-ene-4-ene-steroid isomerase, 3-oxo-delta(5)-steroid isomerase, 5-pregnene-3,20-dione isomerase, steroid 5-4-ene-isomerase, delta(5)-3-ketosteroid isomerase (26 Jun 1999) |
| steroid diabetes | Diabetes mellitus produced by pharmacological doses of steroid hormones, particularly glucocorticoids or oestrogens; characterised by one or more of the typical manifestations of diabetes mellitus. (05 Mar 2000) |
| steroid fever | Fever presumably caused by elevated plasma concentrations of certain pyrogenic steroids; can be produced by administration of etiocholanolone. (05 Mar 2000) |
| steroid finger motif | Family of nuclear transcription factors, most of which are receptors for hormones of the steroid family, for example androgen, oestrogen, glucocorticoid, mineralocorticoid, progesterone, retinoic acid, ecdysone, thyroid hormone and the Drosophila transcription factors knirps, ultraspiracle and seven up. This family contains a conserved domain (the steroid finger motif) containing two C4 type zinc fingers. (18 Nov 1997) |
| steroid hormone | <endocrinology> A group of structurally related hormones, based on the cholesterol molecule. They control sex and growth characteristics, are highly lipophilic and are unique in that their receptors are in the nucleus, rather than on the plasma membrane. Examples: testosterone, oestrogen. (18 Nov 1997) |
| steroid hormones | Those hormone's possessing the steroid ring system; e.g., androgens, oestrogens, adrenocortical hormone's. (05 Mar 2000) |
