The authors would like to publish an erratum to include the additional text in the acknowledgments section.

The complete acknowledgments section should read as:

We thank C. Kakoschke and B. Jaschok-Kentner (Helmholtz Centre for Infection Research, Braunschweig) for recording the 1D ¹³C spectra, Nils Schloerer (NMR Center of the Department of Chemistry, University of Cologne) for recording the 2D ¹H/¹³C spectra, S. Sollazzo (Department of Chemistry, University of Cologne) for recording cPMP stability kinetics, and W. Pfleiderer (University of Constance) and B. Fischer (University of Nagoya) for helpful discussions.
