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

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. Our objective was to

Identification of cellular targets pertinent for the development of effective therapies against pathological pain constitutes a difficult challenge. We combined several approaches to show that 3alpha-hydroxysteroid oxido-reductase (3alpha-HSOR), abundantly expressed in the spinal cord (SC), is a key target, the
