Terpentetriene synthase - Misplaced Pages

Terpentetriene synthase (EC 4.2.3.36, Cyc2) is an enzyme with systematic name terpentedienyl-diphosphate diphosphate-lyase (terpentetriene-forming). This enzyme catalyses the following chemical reaction

terpentedienyl diphosphate

\rightleftharpoons

terpentetriene + diphosphate

This enzyme requires Mg for maximal activity but can use Mn, Fe or Co to a lesser extent.
