Structural basis of the stereoselective formation of the spirooxindole ring in the biosynthesis of citrinadins
Prenylated indole alkaloids contain spirooxindole rings with a 3R or 3S carbon stereocenter, which determines their bioactivities, but the biocatalytic mechanism controlling the 3R- or 3S-spirooxindole formation was unclear. Here, the authors report the biochemical and structural characterization of...

| Sumario: | Prenylated indole alkaloids contain spirooxindole rings with a 3R or 3S carbon stereocenter, which determines their bioactivities, but the biocatalytic mechanism controlling the 3R- or 3S-spirooxindole formation was unclear. Here, the authors report the biochemical and structural characterization of the oxygenase/semipinacolase CtdE that catalyses the 3S-spirooxindole construction in the biosynthesis of 21R-citrinadin A. |
