Shionone synthase

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


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

The enzyme gives traces of four other triterpenoids
