(3S)-2,3-epoxy-2,3-dihydrosqualene hydro-lyase (lupan-3beta,20-diol forming)
The reaction occurs in the reverse direction. The recombinant enzyme from Arabidopsis thaliana gives a 1:1 mixture of lupeol and lupan-3beta,20-diol with small amounts of beta-amyrin, germanicol, taraxasterol and psi-taraxasterol. See EC 5.4.99.41 (lupeol synthase).
