Oxidative cleavage of the cyclopentane ring gives rise to a subclass known as secoiridoids, which are often intermediates in the biosynthesis of terpenoid indole alkaloids (TIA).
WebBiosynthesis of Iridoids and Secoiridoids. Research on iridoids began with the discovery of asperuloside (1) (an iridoid glucoside) in 1848 and gentiopicroside (2) (a secoiridoid glucoside) in 1862. However, it was only in the late 1950’s that the structures of the compounds of this series began to be elucidated. WebExpression of the early MIA pathway in these lines produces a more favorable product profile. Strictosidine biosynthesis was successfully reconstituted, with the best yields obtained by the co-expression of 14 enzymes, of which a major latex protein-like enzyme (MLPL) from Nepeta (catmint) is critical for improving flux through the iridoid pathway.
