Reaction on EC 4.2.3.55 - (S)-beta-bisabolene synthase
Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
(S)-beta-bisabolene is a stable intermediate. (S)-beta-Macrocarpene formation requires a protonation of the intermediate
(2E,6E)-farnesyl diphosphate = (S)-beta-bisabolene + diphosphate
The synthesis of (S)-beta-macrocarpene from (2E,6E)-farnesyl diphosphate proceeds in two steps. The first step is the cyclization to (S)-beta-bisabolene. The second steps is the isomerization to (S)-beta-macrocarpene (c.f. EC 5.5.1.a, (S)-beta-macrocarpene synthase). The enzyme requires Mg2+ or Mn2+ for activity.
