Friedelin synthase

Friedelin synthase is an enzyme with systematic name (3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, friedelin-forming). This enzyme catalyses the following chemical reaction


 * (3S)-2,3-epoxy-2,3-dihydrosqualene $$\rightleftharpoons$$ friedelin

The enzyme from Kalanchoe daigremontiana also gives traces of other triterpenoids.
