Symbol/Gene Name:  hmp

Alias:  3-ketosteroid-9-alpha-monooxygenase, ferredoxin reductase component, 3-ketosteroid-9-alpha-hydroxylase, ferredoxin reductase component, KSH, Androsta-1, 4-diene-3, 17-dione 9-alpha-hydroxylase, Rieske-type oxygenase, RO

Uniprot: P9WJ93

Background: Involved in the degradation of cholesterol. Catalyzes the introduction of a 9a-hydroxyl moiety into 1,4-androstadiene-3,17-dione (ADD) to yield the 9alpha-hydroxy-1,4-androstadiene-3,17-dione (9OHADD) intermediate which spontaneously form 3-hydroxy-9,10-seconandrost-1,3,5(10)-triene-9,17-dione (HSA) via the meta-cleavage of ring B with concomitant aromatization of ring A. KSH is also able to use 4-androstene-3,17-dione (AD), 3-oxo-23,24-bisnorcholesta-4-en-22-oate (4-BNC), 3-oxo-23,24-bisnorcholesta-1,4-dien-22-oate(4-BNC), 3-oxo-23,24-bisnorcholesta-4-en-22-oyl-coenzyme A thioester (4-BNC-CoA) and 3-oxo-23,24-bisnorcholesta-1,4-dien-22-oyl-coenzyme A thioester(4-BNC-CoA) as substrates.
