Entry
EC 4.2.3.64                 Enzyme                                 

Name
(+)-epicubenol synthase;
farnesyl pyrophosphate cyclase (ambiguous)
Class
Lyases;
Carbon-oxygen lyases;
Acting on phosphates
BRITE hierarchy
Sysname
(2E,6E)-farnesyl-diphosphate diphosphate-lyase [(+)-epicubenol-forming]
Reaction(IUBMB)
(2E,6E)-farnesyl diphosphate + H2O = (+)-epicubenol + diphosphate [RN:R09617]
Reaction(KEGG)
Substrate
(2E,6E)-farnesyl diphosphate [CPD:C00448];
H2O [CPD:C00001]
Product
(+)-epicubenol [CPD:C19744];
diphosphate [CPD:C00013]
Comment
Requires Mg2+. In the bacteria Streptomyces and the liverwort Heteroscyphus the (+)-isomer is formed in contrast to higher plants where the (-)-isomer is formed.
