Cloning and expression of chicken 20-hydroxysteroid dehydrogenase.
The ligand specificity and activation of steroid receptors depend considerably on the enzymatic activities involved in local pre-receptor synthesis and the metabolism of the steroids. Several enzymes in particular, steroid dehydrogenases have been shown to participate in this process. Here we report the isolation of 20-hydroxysteroid dehydrogenase (ch20HSD) cDNA from chicken intestine and the d...
متن کاملExpression cloning and characterization of human 17 beta-hydroxysteroid dehydrogenase type 2, a microsomal enzyme possessing 20 alpha-hydroxysteroid dehydrogenase activity.
17 beta-Hydroxysteroid dehydrogenase (17 beta-HSD) is an enzyme crucial to the regulation of intracellular levels of biologically active steroid hormones in a variety of tissues. Here, we report the isolation, structure, and characterization of a cDNA encoding the human 17 beta-HSD type 2. A 1.4-kilobase cDNA was identified, and DNA sequence analysis indicated that 17 beta-HSD type 2 was a prot...
متن کاملCharacterization of a human 20 -hydroxysteroid dehydrogenase
It has been suggested that 20 -hydroxysteroid dehydrogenase (20 -HSD) is a T-cell differentiation marker in mice. In the human, this enzyme has generally been associated with types 1 and 2 17 -HSDs, which belong to the short-chain alcohol dehydrogenase family, whereas the rat, rabbit, pig and bovine 20 -HSDs are members of the aldoketo reductase superfamily, which also includes the 3 -HSD famil...
متن کاملHexose-6-phosphate dehydrogenase confers oxo-reductase activity upon 11 beta-hydroxysteroid dehydrogenase type 1.
Two isozymes of 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD) interconvert active cortisol and inactive cortisone. 11 beta-HSD2 (renal) acts only as a dehydrogenase, converting cortisol to cortisone. 11 beta-HSD1 (liver) is a bi-directional enzyme in cell homogenates, whereas in intact cells it typically displays oxo-reductase activity, generating cortisol from cortisone. We recently estab...
متن کاملMolecular cloning of cDNA for rat ovarian 20 alpha-hydroxysteroid dehydrogenase (HSD1).
20 alpha-Hydroxysteroid dehydrogenase (20 alpha-HSD, EC 1.1.1.149) catalyses the conversion of progesterone into 20 alpha-dihydroprogesterone (20 alpha-OHP). Previously, we purified the enzyme (37 kDa) from rat ovary and determined its N-terminal amino acid sequence. In the present study we succeeded in cloning a full-length 20 alpha-HSD cDNA. mRNA was extracted from immature rat ovaries after ...
