(4S) beta phellandrene synthase (geranyl diphosphate cyclizing)

(4S)-beta-phellandrene synthase (geranyl-diphosphate-cyclizing) (EC 4.2.3.52, phellandrene synthase, (−)-beta-phellandrene synthase, (−)-(4S)-beta-phellandrene synthase) is an enzyme with systematic name geranyl-diphosphate diphosphate-lyase (cyclizing; (4S)-beta-phellandrene-forming). This enzyme catalyses the following chemical reaction

This enzyme requires ion Mn²⁺.
