Model of Esperamicin A1
Esperamicin A1 -- an enediyne -- binds to DNA immediately prior to activation of its "warhead" (shown in orange), which will cleave the DNA. Enediynes are naturally-occurring molecules commonly called biological warheads for their ability to bind to and split tumors' DNA backbones.
