Comment typeDescription
Catalytic Activity17-alpha-hydroxyprogesterone = androst-4-ene- 3,17-dione + acetaldehyde.
Catalytic ActivityA C(21)-steroid + (reduced NADPH--hemoprotein reductase) + O(2) = a 17-alpha-hydroxy-C(21)-steroid + (oxidized NADPH--hemoprotein reductase) + H(2)O.
CofactorName=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
Enzyme RegulationRegulated predominantly by intracellular cAMP levels.
FunctionConversion of pregnenolone and progesterone to their 17- alpha-hydroxylated products and subsequently to dehydroepiandrosterone (DHEA) and androstenedione. Catalyzes both the 17-alpha-hydroxylation and the 17,20-lyase reaction. Involved in sexual development during fetal life and at puberty.
PathwayLipid metabolism; steroid biosynthesis.
SimilarityBelongs to the cytochrome P450 family. {ECO:0000305}.
Subcellular LocationMembrane {ECO:0000305}.
