Accepted name: α-gurjunene synthase
Reaction: (2E,6E)-farnesyl diphosphate = (-)-α-gurjunene + diphosphate
Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase [(-)-α-gurjunene-forming]
Comments: Initial cyclization probably gives biyclogermacrene in an enzyme bound form which is not released to the medium. The enzyme from Solidago canadensis also forms a small amount of (+)-γ-gurjunene [1].
