Actagardin

Actagardin is a tetracyclic lantibiotic produced by several species of Actinoplanes. It is composed of macrocyclic rings formed by thioether bridges. Actagardin preferably targets Gram-positive bacteria, inhibiting the synthesis of peptidoglycan.Formal Name: D-cysteinyl-L-serylglycyl-L-tryptophyl-L-valyl-L-cysteinyl-(2S,3S)-2-amino-3-mercaptobutanoyl-L-leucyl-(2S,3S)-2-amino-3-mercaptobutanoyl-L-isoleucyl-L-alpha-glutamyl-L-cysteinylglycyl-(2S,3S)-2-amino-3-mercaptobutanoyl-L-valyl-L-isoleucyl-L-cysteinyl-L-alanyl-L-cysteine, cyclic (1->6),(7->12),(9->17),(14->19)-tetrakis(thioether) S14-oxide.
