Alpha-seco-amyrin synthase

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


 * (3S)-2,3-epoxy-2,3-dihydrosqualene $$\rightleftharpoons$$ alpha-seco-amyrin

The enzyme from Arabidopsis thaliana is multifunctional.
