Sysname
3beta-hydroxy-Delta5-steroid:NAD+ 3-oxidoreductase
Reaction(IUBMB)
a 3beta-hydroxy-Delta5-steroid + NAD+ = a 3-oxo-Delta5-steroid + NADH + H+ [RN:R03176]
Reaction(KEGG)
Substrate
3beta-hydroxy-Delta5-steroid [CPD:C03836];
NAD+ [CPD:C00003]
Product
3-oxo-Delta5-steroid [CPD:C01034];
NADH [CPD:C00004];
H+ [CPD:C00080]
Comment
This activity is found in several bifunctional enzymes that catalyse the oxidative conversion of Delta5-3-hydroxy steroids to a Delta4-3-oxo configuration. This conversion is carried out in two separate, sequential reactions; in the first reaction, which requires NAD+, the enzyme catalyses the dehydrogenation of the 3beta-hydroxy steroid to a 3-oxo intermediate. In the second reaction the reduced coenzyme, which remains attached to the enzyme, activates the isomerization of the Delta5 form to a Delta4 form (cf. EC 5.3.3.1, steroid Delta-isomerase). Substrates include dehydroepiandrosterone (which is converted into androst-5-ene-3,17-dione), pregnenolone (converted to progesterone) and cholest-5-en-3-one, an intermediate of cholesterol degradation.
