EC 4.2.3.195     
Accepted name: rhizathalene A synthase
Reaction: geranylgeranyl diphosphate = rhizathalene A + diphosphate
For diagram of miscellaneous diterpenoid biosynthesis, click here
Other name(s): TPS08 (gene name)
Systematic name: geranygeranyl-diphosphate diphosphate-lyase (rhizathalene A-forming)
Comments: The enzyme was identified in the roots of the plant Arabidopsis thaliana (thale cress). The product is a semivolatile diterpene that acts as a local antifeedant in belowground direct defense against root-feeding insects.
