A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 4.2.3.194

Accepted Name
(-)-drimenol synthase.
Alternative Name(s)
Drimenol cyclase.
Farnesyl pyrophosphate:drimenol cyclase.
Reaction catalysed
(2E,6E)-farnesyl diphosphate + H(2)O <=> (-)-drimenol + diphosphate
Comment(s)
  • Isolated from the plants Valeriana officinalis (valerian) and Persicaria hydropiper (water pepper).
  • The enzyme does not act on farnesol or drimenol diphosphate.
  • Using 18-oxygen labelled water 18-oxygen was incorporated suggesting involvement of a stabilized carbocation or an equivalent species.
  • Formerly EC 3.1.7.7.
