Application
Binds to the DNA-recognizing domain of ADP-ribosyltransferase and preferentially destabilizes one of the two zinc finger polypeptide complexes. The affected enzyme loses almost all activity, but still binds to DNA.

PPTases (phosphopantetheinyl transferases) are of great interest owing to their essential roles in activating fatty acid, polyketide and non-ribosomal peptide synthetase enzymes for both primary and secondary metabolism, as well as an increasing number of biotechnological applications. However, existing techniques
