IntEnz Enzyme Nomenclature
EC 5.4.99.55

Names

Accepted name:
δ-amyrin synthase
Other name:
SlTTS2 (gene name)
Systematic name:
(3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, δ-amyrin-forming)

Reaction

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 5.4.99.40, α-amyrin synthase and EC 5.4.99.39, β-amyrin synthase.
