Accepted name: δ-amyrin synthase
Reaction: (3S)-2,3-epoxy-2,3-dihydrosqualene = δ-amyrin
Other name(s): SlTTS2 (gene name)
Systematic name: (3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, δ-amyrin-forming)
Comments: The enzyme from tomato (Solanum lycopersicum) gives 48% δ-amyrin, 18% α-amyrin, 13% β-amyrin and traces of three or four other triterpenoid alcohols [1]. See also EC, α-amyrin synthase and EC, β-amyrin synthase.
