In enzymology, a cycloeucalenol cycloisomerase (EC 5.5.1.9) is an enzyme that catalyzes the chemical reaction
- cycloeucalenol obtusifoliol
Hence, this enzyme has one substrate, , and one product, obtusifoliol.
This enzyme belongs to the family of isomerases, specifically the class of intramolecular lyases. The systematic name of this enzyme class is cycloeucalenol lyase (cyclopropane-decyclizing). This enzyme is also called cycloeucalenol---obtusifoliol isomerase. This enzyme participates in biosynthesis of steroids.
