Cerulenin Reveals Leucomycin Biosynthesis
2026-08-12
Takeshima, Kitao, and Omura used cerulenin as a pathway-selective perturbation to show that Leucomycin biosynthesis in Streptomyces kitasatoensis depends on condensation chemistry analogous to fatty acid synthesis. Their combination of inhibitor exposure, radiolabeled acetate tracing, and macromolecular-synthesis controls provided early functional evidence for a polyketide origin of the leucomycin aglycone.
