Accepted name: β-phellandrene synthase (neryl-diphosphate-cyclizing)
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 [1].

Monoterpenes in the glandular trichomes of tomato are synthesized from a neryl diphosphate precursor rather than geranyl diphosphate. Proc. Natl. Acad. Sci. USA 106 (2009) 10865–10870.
