KEGG   ENZYME: 4.2.3.55Help
Entry
EC 4.2.3.55                 Enzyme                                 

Name
(S)-beta-bisabolene synthase
Class
Lyases;
Carbon-oxygen lyases;
Acting on phosphates
BRITE hierarchy
Sysname
(2E,6E)-farnesyl-diphosphate diphosphate-lyase [(S)-beta-bisabolene-forming]
Reaction(IUBMB)
(2E,6E)-farnesyl diphosphate = (S)-beta-bisabolene + diphosphate [RN:R09623]
Reaction(KEGG)
Substrate
(2E,6E)-farnesyl diphosphate [CPD:C00448]
Product
(S)-beta-bisabolene [CPD:C19751];
diphosphate [CPD:C00013]
Comment
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 step is the isomerization to (S)-beta-macrocarpene (cf. EC 5.5.1.17, (S)-beta-macrocarpene synthase). The enzyme requires Mg2+ or Mn2+ for activity.
