IntEnz Enzyme Nomenclature
EC 4.2.3.52

Names

Accepted name:
(4S)-β-phellandrene synthase (geranyl-diphosphate-cyclizing)
Other names:
phellandrene synthase
(−)-β-phellandrene synthase
(−)-(4S)-β-phellandrene synthase
Systematic name:
geranyl-diphosphate diphosphate-lyase [cyclizing; (4S)-β-phellandrene-forming]

Reaction

Cofactor

Comments:

Requires Mn2+. Mg2+ is not effective [1]. Some (−)-α-phellandrene is also formed [3]. The reaction involves a 1,3-hydride shift [4].
