The 3β-hydroxysteroid dehydrogenase/Δ5-Δ4 isomerase (3βHSD) enzyme catalyzes the oxidation and isomerization of Δ5−3β-hydroxysteroid precursors into Δ4-ketosteroids, thus leading to the formation of all classes of steroid hormones. In addition, 3βHSD catalyzes the interconversion of 3β-hydroxy- and 3-keto-5α-androstane steroids. Clinical observations in patients with 3βHSD deficiency as well as our recent data obtained by Southern blot analysis using a human placental 3βHSD cDNA (type I) as probe suggested the existence of multiple related 3βHSD isoenzymes. We now report the isolation and characterization of a second type of cDNA clone (arbitrarily designated type II) encoding 3βHSD after screening of a human adrenal λgt22A library. The nucleotide sequence of 1676 basepairs of human 3βHSD type II cDNA predicts a protein of 371 amino acids with a calculated molecular mass of 41,921 daltons, which displays 93.5% and 96.2% homology with human placental type I and rhesus macaque ovary 3βHSD deduced proteins, ...
