Delta-amyrin synthase explained

δ-Amyrin synthase
Ec Number:	5.4.99.55

δ-Amyrin synthase (SlTTS2 (gene)) is an enzyme with systematic name (3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, delta-amyrin-forming).^[1] 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.
