Enzyme Information

1.3.1.99
Iridoid synthase.
based on mapping to UniProt K7WDL7
(6E)-8-oxogeranial + NAD(P)H = cis-trans-nepetalactol + NAD(P)(+).
-!- Isolated from the plant Catharanthus roseus. -!- The reaction may involve cyclization via a Diels-Alder or Michael reaction. -!- Iridoids are involved in the biosynthesis of many indole alkaloids. -!- The cyclic hemiacetal is readily hydrolyzed to the corresponding dial.
