Entry
EC 1.1.1.319                Enzyme                                 
Name
isoeugenol synthase;
IGS1;
t-anol/isoeugenol synthase 1
Class
Oxidoreductases;
Acting on the CH-OH group of donors;
With NAD+ or NADP+ as acceptor
Sysname
eugenol:NADP+ oxidoreductase (coniferyl acetate reducing)
Reaction(IUBMB)
isoeugenol + acetate + NADP+ = coniferyl acetate + NADPH + H+ [RN:R09931]
Reaction(KEGG)
R09931;
(other) R10289
Substrate
isoeugenol [CPD:C10469];
acetate [CPD:C00033];
NADP+ [CPD:C00006]
Product
coniferyl acetate [CPD:C20225];
NADPH [CPD:C00005];
H+ [CPD:C00080]
Comment
The enzyme acts in the opposite direction. In Ocimum basilicum (sweet basil), Clarkia breweri and Petunia hybrida only isoeugenol is formed [1,2]. However in Pimpinella anisum (anise) only anol is formed in vivo, although the cloned enzyme does produce isoeugenol [3].
