Inversion of C3 stereochemistry of monoterpenoid indole alkaloids (MIAs) has to occur at some point during their biosynthesis; however, the mechanism has remained unresolved. Here, the authors report an oxidase–reductase enzyme pair encoded within a gene cluster and demonstrate their collaborative role in inverting MIA C3 stereochemistry.
