General annotation (Comments)

Function	3-beta-HSD is a bifunctional enzyme, that catalyzes the oxidative conversion of Delta(5)-ene-3-beta-hydroxy steroid, and the oxidative conversion of ketosteroids. The 3-beta-HSD enzymatic system plays a crucial role in the biosynthesis of all classes of hormonal steroids.
Catalytic activity	A 3-beta-hydroxy-Delta(5)-steroid + NAD+ = a 3-oxo-Delta(5)-steroid + NADH. A 3-oxo-Delta(5)-steroid = a 3-oxo-Delta(4)-steroid.
Pathway	Lipid metabolism; steroid biosynthesis.
Subcellular location	Endoplasmic reticulum membrane; Single-pass membrane protein. Mitochondrion membrane; Single-pass membrane protein.
Tissue specificity	Adrenal glands, testes and ovaries.
Sequence similarities	Belongs to the 3-beta-HSD family.
