ID   1.3.1.122
DE   (S)-8-oxocitronellyl enol synthase.
AN   iridoid synthase.
CA   (1) (S)-8-oxocitronellyl enol + NADP(+) = (6E)-8-oxogeranial + H(+) +
CA   NADPH.
CA   (2) (S)-8-oxocitronellyl enol + NAD(+) = (6E)-8-oxogeranial + H(+) +
CA   NADH.
CC   -!- Isolated from the plants Catharanthus roseus, Olea europaea (common
CC       olive), and several Nepeta species.
CC   -!- The enzyme reduces 8-oxogeranial, generating an unstable product that
CC       is subsequently cyclized into several possible products, either non-
CC       enzymically or by dedicated cyclases.
CC   -!- The products, known as iridoids, are involved in the biosynthesis of
CC       many indole alkaloids. cf. EC 1.3.1.123.
CC   -!- Formerly EC 1.3.1.99.
