IUBMB Enzyme Nomenclature

EC 4.2.3.51

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].
