Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

The 3-beta-HSD enzymatic system plays a crucial role in the biosynthesis of all classes of hormonal steroids. HSD VII is active against four 7-alpha-hydroxylated sterols. Does not metabolize several different C(19/21) steroids as substrates. Involved in bile acid synthesis.

Catalytic activityi

3-beta-hydroxy-Delta(5)-steroid + NAD+ = 3-oxo-Delta(5)-steroid + NADH.
Cholest-5-ene-3-beta,7-alpha-diol + NAD+ = 7-alpha-hydroxycholest-4-en-3-one + NADH.
