Other name(s): CAMS1; LUP3 (gene name)
Systematic name: (3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, camelliol-C-forming)
Comments: The product is 97% camelliol, 2% achilleol A and 0.2% β-amyrin. Achilleol is an isomer of camelliol C with a 4-methylenecyclohexanol ring system. This enzyme probably evolved from EC 5.4.99.39, β-amyrin synthase.
