EC 4.2.3.80     
Accepted name: α-longipinene synthase
Reaction: (2E,6E)-farnesyl diphosphate = α-longipinene + diphosphate

Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (α-longipinene-forming)
Comments: The enzyme from Norway spruce produces longifolene as the main product (cf. EC 4.2.3.58, longifolene synthase). α-Longipinene constitutes about 15% of the total products.
