Application

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

Biochem/physiol Actions

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.

Packaging
