Protein

Cholesterol oxidase

Gene

choB

Organism
Brevibacterium sterolicum
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the oxidation and isomerization of cholesterol to cholestenone (4-cholesten-3-one), which is an initial step in the cholesterol degradation process.

Catalytic activityi

Cholesterol + O2 = cholest-5-en-3-one + H2O2.
A 3-oxo-Delta(5)-steroid = a 3-oxo-Delta(4)-steroid.
