Notes: Calicheamicin γ1 is a polyketide synthase-derived enediyne that has been found in M. echinospora.{69845} It is composed of carbohydrate and aromatic moieties, which bind to the minor groove in DNA, and a warhead moiety that aromatizes and oxidatively induces double-stranded DNA scission in cell-free assays.{69846,69847}
