Glossary: valerianol = 2-[(2R,8R,8aS)-8,8a-dimethyl-1,2,3,4,6,7,8,8a-octahydronaphthalen-2-yl]propan-2-ol
Other name(s): ChTPS1 (gene name); CsiTPS8 (gene name)
Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (valerianol-forming)
Comments: The enzyme was characterized from the trees Camellia hiemalis and Camellia sinensis (black tea). The enzyme from Camellia hiemalis produces (2Z,6E)-hedycaryol as a minor product.
