Monoterpene indole alkaloid pathway.

, 2012
The key intermediate strictosidine is formed by condensation of tryptamine, which contributes the indole ring, and secologanin, which is produced from the monoterpene geraniol.

Improved expression of His₆-tagged strictosidine synthase cDNA for chemo-enzymatic alkaloid diversification

, 2010
Strictosidine synthase (STR1) catalyzes the stereoselective formation of 3α(S)‐strictosidine from tryptamine and secologanin. Strictosidine is the key intermediate in the biosynthesis of 2,000 plant monoterpenoid indole alkaloids, and it is a key ...
