General annotation (Comments)

Function

Conversion 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.

Catalytic activity

A steroid + AH2 + O2 = a 17-alpha-hydroxysteroid + A + H2O.

Cofactor

Heme group By similarity.

Enzyme regulation

Regulated predominantly by intracellular cAMP levels.

Pathway

Lipid metabolism; steroid biosynthesis.

Subcellular location

Membrane Potential. Membrane; Single-pass membrane protein.

Sequence similarities

Belongs to the cytochrome P450 family.
