Application
来源于假单胞菌 睾丸激素的3α-羟基类固醇脱氢酶已被用于:
- 制备复合电极平台,以用于测定雄甾酮
- 磷酸钾缓冲液中,以用于血清中胆汁酸的生物发光测定
- 通过酶法测定总胆汁盐
Biochem/physiol Actions
3α-羟基类固醇脱氢酶 (3α-HSD) 可以帮助调节雄激素靶组织中雄激素受体 (AR) 的占据。它也可阻碍雄激素的作用。

Developing methods that result in targeting of therapeutic molecules in gene therapies to target tissues has importance, as targeting can increase efficacy and decrease off target-side-effects. Work from my laboratory previously showed that the extracellular matrix protein Del1 is organized

Two novel lactones, Cephalosporolides H (1) and 1 (2), were isolated from the lyophilized culture broth of the marine-derived fungus, Penicillium sp. The structures were elucidated on the basis of extensive 1D- and 2D-NMR, as well as HRESI-MS spectroscopic analyses.

Experimentally determined protein tertiary structures are rapidly accumulating in a database, partly due to the structural genomics projects. Included are proteins of unknown function, whose function has not been investigated by experiments and was not able to be predicted by

Glucocorticoids are metabolized by 11beta-hydroxysteroid dehydrogenase 1 (11betaHSD1) and the A-ring reductases (5alpha- and 5beta-reductases). Dysregulation of these enzymes has been reported in liver and adipose tissue in obese humans and animals, potentially leading to altered intracellular glucocorticoid concentrations and

Dihydrotestosterone (DHT), the primary active androgen in peripheral target tissues, is metabolized by 3alpha-hydroxysteroid dehydrogenase type III (3alpha-HSD), encoded by the AKR1C2 gene, forming 5alpha-androstane-3alpha,17beta-diol (3alpha-diol). 3alpha-HSD may play a role in the pathogenesis of hirsutism.
