애플리케이션

3α-Hydroxysteroid Dehydrogenase from Pseudomonas testosterone has been used:
  • in the preparation of composite electrode platform to for the determination of androsterone
  • in potassium phosphate buffer for the bioluminescent assay of bile acids in serum
  • for total bile salts assay using an enzymatic method

생화학적/생리학적 작용

3α-hydroxysteroid dehydrogenase (3α-HSD) may help to modulate the occupancy of the androgen receptor (AR) in androgen target tissues. It may also act in hindering androgen action.

단위 정의

One unit will oxidize 1.0 μmole of androsterone per min at pH 8.9 at 25 °C in the presence of β-NAD+.

물리적 형태

Lyophilized powder containing potassium phosphate buffer salt, EDTA, and DL-dithiothreitol

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.

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
