Abstract

We have developed the first selective fluorescent chemosensor (PyDPA) for (p) ppGpp, a bacterial and plant alarmone. By using pyrene-excimer fluorescence, PyDPA shows very good selectivity for (p) ppGpp from among other nucleotides in water. PyDPA was used for the real-time detection of in vitro ppGpp synthesis by bacterial ribosomal complexes.
