EC 5.4.99.65     
Accepted name: pre-α-onocerin synthase
Reaction: (3S,22S)-2,3:22,23-diepoxy-2,3,22,23-tetrahydrosqualene = pre-α-onocerin
Glossary: pre-α-onocerin = (21S)-21,22-epoxypolypoda-8(26)-13,17-trien-3β-ol
Other name(s): LCC
Systematic name: (3S,22S)-2,3:22,23-diepoxy-2,3,22,23-tetrahydrosqualene mutase (cyclizing, pre-α-onocerin-forming)
Comments: Isolated from the plant Lycopodium clavatum. The enzyme does not act on (3S)-2,3-epoxy-2,3-dihydrosqualene and does not form any α-onocerin.
