Accepted name: cis-abienol synthase
Reaction: (13E)-8α-hydroxylabd-13-en-15-yl diphosphate = cis-abienol + diphosphate
Glossary: cis-abienol = (12Z)-labda-12,14-dien-8α-ol
(13E)-8α-hydroxylabd-13-en-15-yl diphosphate = 8-hydroxycopalyl diphosphate
Other name(s): Z-abienol synthase; CAS; ABS
Systematic name: (13E)-8α-hydroxylabd-13-en-15-yl-diphosphate-lyase (cis-abienol-forming)
Comments: Isolated from the plants Abies balsamea (balsam fir) [1] and Nicotiana tabacum (tobacco) [2].
