Reaction: geranyl diphosphate = myrcene + diphosphate

myrcene: a monoterpenoid
Systematic name: geranyl-diphosphate diphosphate-lyase (myrcene-forming)
Comments: A recombinant enzyme (also known as a monoterpene synthase or cyclase) from the grand fir (Abies grandis) requires Mn2+ and K+ for activity. Mg2+ is essentially ineffective as the divalent metal ion cofactor.
