Beta-seco-amyrin synthase

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


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

The enzyme from Arabidopsis thaliana is multifunctional.
