In this issue of Chemistry & Biology, a novel priming mechanism is proposed for aromatic polyketide biosynthesis, with an iterative type I polyketide synthase generating a starter unit primed for a type II polyketide synthase . This novel priming system participates in hedamycin biosynthesis, a DNA alkylating agent.
