Ancient gene clusters govern the initiation of monoterpenoid indole alkaloid biosynthesis and C3 stereochemistry inversion. [PDF]

Nat Commun
The inversion of C3 stereochemistry in monoterpenoid indole alkaloids (MIAs), derived from the central precursor strictosidine (3S), is essential for producing pharmacologically important 3 R MIAs and spirooxindoles such as reserpine.
