Abstract
The (seco)iridoids and their derivatives, the
monoterpenoid indole alkaloids (MIAs), form two large
families of plant-derived bioactive compounds with a wide
spectrum of high-value pharmacological and
insect-repellent activities. Vinblastine and vincristine,
MIAs used as anticancer drugs, are produced by
Catharanthus roseus in extremely low levels, leading to
high market prices and poor availability. Their
biotechnological production is hampered by the
fragmentary knowledge of their biosynthesis. Here we
report the discovery of the last four missing steps of
the (seco)iridoid biosynthesis pathway. Expression of the
eight genes encoding this pathway, together with two
genes boosting precursor formation and two downstream
alkaloid biosynthesis genes, in an alternative plant
host, allows the heterologous production of the complex
MIA strictosidine. This confirms the functionality of all
enzymes of the pathway and highlights their utility for
synthetic biology programmes towards a sustainable
biotechnological production of valuable (seco)iridoids
and alkaloids with pharmaceutical and agricultural
applications
