SYSTEMATIC NAME
IUBMB Comments
geranyl-diphosphate diphosphate-lyase [cyclizing, (+)-(4R)-limonene-forming]
Forms the first step of carvone biosynthesis in caraway. The enzyme from Carum carvi (caraway) seeds requires a divalent metal ion (preferably Mn2+) for catalysis. This enzyme occurs in Citrus, Carum (caraway) and Anethum (dill); (-)-limonene, however, is made in the fir, Abies, and mint, Mentha, by EC 4.2.3.16, (4S)-limonene synthase.
