Other name(s): TPS6; TPS11; (S)-β-macrocarpene lyase (decyclizing)
Systematic name: (S)-β-macrocarpene lyase (ring-opening)
Comment:The synthesis of (S)-β-macrocarpene from (2E,6E)-farnesyl diphosphate proceeds in two steps. The first step is the cyclization to (S)-β-bisabolene (cf. EC 188.8.131.52, (S)-β-bisabolene synthase). The second step is the isomerization to (S)-β-macrocarpene. Links to other databases: BRENDA, EXPASY, KEGG, Metacyc, CAS registry number:
