Cycloartenol synthase

In enzymology, a cycloartenol synthase is an enzyme that catalyzes the chemical reaction


 * (S)-2,3-epoxysqualene $$\rightleftharpoons$$ cycloartenol

Hence, this enzyme has one substrate, (S)-2,3-epoxysqualene, and one product, cycloartenol.

This enzyme is an oxidosqualene cyclase and belongs to the family of isomerases, specifically those intramolecular transferases transferring other groups. This enzyme participates in biosynthesis of steroids.

Nomenclature
The systematic name of this enzyme class is: Other names in common use include:
 * (S)-2,3-epoxysqualene mutase (cyclizing, cycloartenol-forming).
 * 2,3-epoxysqualene cycloartenol-cyclase
 * squalene-2,3-epoxide-cycloartenol cyclase
 * 2,3-epoxysqualene cycloartenol-cyclase
 * 2,3-epoxysqualene-cycloartenol cyclase
 * 2,3-oxidosqualene-cycloartenol cyclase
