Beta-phellandrene synthase (neryl-diphosphate-cyclizing)

β-Phellandrene synthase (neryl-diphosphate-cyclizing) (EC 4.2.3.51, phellandrene synthase 1, PHS1, monoterpene synthase PHS1) is an enzyme with systematic name neryl-diphosphate diphosphate-lyase (cyclizing; beta-phellandrene-forming). This enzyme catalyses the following chemical reaction


 * neryl diphosphate $$\rightleftharpoons$$ β-phellandrene + diphosphate

The enzyme from Solanum lycopersicum has very poor affinity with geranyl diphosphate.
