Delta-amyrin synthase

δ-Amyrin synthase (, SlTTS2 (gene)) is an enzyme with systematic name (3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, delta-amyrin-forming). This enzyme catalyses the following chemical reaction


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

The enzyme from tomato (Solanum lycopersicum) gives delta-amyrin, alpha-amyrin, beta-amyrin.
