Comments

FUNCTION: Along with the 3 alpha-hydroxysteroid dehydrogenase and 3-oxo-reductase activities towards a variety of cis or trans fused A/B ring steroids, it also reduces several xenobiotic carbonyl compounds, including a metyrapone-based class of insecticides, to the respective alcohol metabolites.
CATALYTIC ACTIVITY: Androsterone + NAD(P)⁺ = 5-alpha-androstane-3,17-dione + NAD(P)H.
SUBCELLULAR LOCATION: Cytoplasm.
INDUCTION: By steroids.
SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR) family.
