Isolated from an ecotype of the plant Arabidopsis thaliana from Cape Verde Islands. The enzyme also gives (3E,7E)-dolabella-3,7-dien-18-ol and traces of other terpenoids. cf. EC 4.2.3.167 dolabella-3,7-dien-18-ol synthase.
The expected taxonomic range for this enzyme is: Arabidopsis thaliana

Substrates: reaction presumably proceeds via dephosphorylation of geranylgeranyl diphosphate and the formation of a dolabelanyl carbocation, which is then converted to dolathaliatriene by a Wagner-Meerwein rearrangement and deprotonation or directly to dolabelladienol by quenching with water, reaction of EC 4.2.3.167 Products: -
TPS20 compounds occur in all tissues of ecotype Cvi but are absent in the Col ecotype because of deletion and substitution mutations in the Col TPS20 sequence
the primary TPS20 diterpene products retard the growth of the root rot pathogen Pythium irregulare but only at concentrations exceeding those in planta
