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。

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

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

3alpha-Hydroxysteroid dehydrogenase/carbonyl reductase (3alpha-HSD/CR) from Comamonas testosteroni belongs to the short chain dehydrogenase/reductase (SDR) protein superfamily and catalyzes the oxidoreduction of a variety of steroid substrates, including the steroid antibiotic fusidic acid. The enzyme also mediates the carbonyl reduction of
