Protein

Steroid 17-alpha-hydroxylase/17,20 lyase

Gene
CYP17A1, CYP17
Organism
Capra hircus (Goat)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

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 By similarity.

Catalytic activityi

A C(21)-steroid + (reduced NADPH--hemoprotein reductase) + O2 = a 17-alpha-hydroxy-C(21)-steroid + (oxidized NADPH--hemoprotein reductase) + H2O.
17-alpha-hydroxyprogesterone = androst-4-ene-3,17-dione + acetaldehyde.

Cofactori

Heme group By similarity.
