α-Amyrin synthase (EC 5.4.99.40, 2,3-oxidosqualene alpha-amyrin cyclase, mixed amyrin synthase) is an enzyme with systematic name (3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, alpha-amyrin-forming).[1] This enzyme catalyses the following chemical reaction

(3S)-2,3-epoxy-2,3-dihydrosqualene [math]\displaystyle{ \rightleftharpoons }[/math] alpha-amyrin

This multifunctional enzyme produces both alpha- and beta-amyrin.
