Reaction: neryl diphosphate = β-phellandrene + diphosphate
Other name(s): phellandrene synthase 1; PHS1; monoterpene synthase PHS1
Systematic name: neryl-diphosphate diphosphate-lyase [cyclizing; β-phellandrene-forming]
Comments: The enzyme from Solanum lycopersicum has very poor affinity with geranyl diphosphate as substrate. Catalyses the formation of the acyclic myrcene and ocimene as major products in addition to β-phellandrene .
