EC 4.2.3.160     
Accepted name: (2S,3R,6S,9S)-(–)-protoillud-7-ene synthase
Reaction: (2E,6E)-farnesyl diphosphate = (2S,3R,6S,9S)-(–)-protoillud-7-ene + diphosphate
Glossary: (2S,3R,6S,9S)-(–)-protoillud-7-ene = (2aS,4aS,7aS,7bR)-3,6,6,7b-tetramethyl-2,2a,4a,5,6,7,7a,7b-octahydro-1H-cyclobuta[e]indene
pentalenene = (3aS,5aS,8aR)-1,4,7,7-tetramethyl-1,2,3,3a,5a,6,7,8-octahydrocyclopenta[c]pentalene
Other name(s): TPS6 (gene name)
Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase [cyclizing, (2S,3R,6S,9S)-(–)-protoillud-7-ene-forming]
Comments: The enzyme has been described from the slime-mould Dictyostelium discoideum. It is specific for (2E,6E)-farnesyl diphosphate. While the major product is the sequiterpene (2S,3R,6S,9S)-(–)-protoillud-7-ene, traces of pentalenene are also formed.
