Comment typeDescription
Catalytic ActivityA 3-beta-hydroxy-Delta(5)-steroid + NAD(+) = a 3-oxo-Delta(5)-steroid + NADH.
Catalytic ActivityA 3-oxo-Delta(5)-steroid = a 3-oxo-Delta(4)- steroid.
Function3-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.
PathwayLipid metabolism; steroid biosynthesis.
SimilarityBelongs to the 3-beta-HSD family. {ECO:0000305}.
Subcellular LocationEndoplasmic reticulum membrane; Single-pass membrane protein. Mitochondrion membrane; Single-pass membrane protein.
Tissue SpecificitySteroidogenic tissues (includes testes, ovaries and adrenal glands).
