ID 5.4.99.65 DE pre-alpha-onocerin synthase. CA (3S,22S)-2,3:22,23-diepoxy-2,3,22,23-tetrahydrosqualene = pre-alpha- CA onocerin. CC -!- Isolated from the plant Lycopodium clavatum. CC -!- The enzyme does not act on (3S)-2,3-epoxy-2,3-dihydrosqualene and CC does not form any alpha-onocerin. DR A0A125SXN1, LCC_LYCCL ; //
