SYSTEMATIC NAME
IUBMB Comments
geranyl-diphosphate diphosphate-lyase (cyclizing, gamma-terpinene-forming)
Isolated from Thymus vulgaris (thyme) [1,2], Citrus limon (lemon) [3], Citrus unshiu (satsuma) [4] and Origanum vulgare (oregano) [5]. Requires Mg2+. Mn2+ less effective. The reaction involves a 1,2-hydride shift. The 5-pro-S hydrogen of geranyl diphosphate is lost. Traces of several other monoterpenoids are formed in addition to gamma-terpinene.
