WebSep 1, 2012 · The cells accumulated P i mostly in the form of polyphosphate (PolyP). In the presence of Mg 2+, the content of PolyP with longer average chain length increased in both yeasts; they both had numerous inclusions fluorescing in the yellow region of the spectrum, typical of DAPI-PolyP complexes. WebA novel fluorescence PPK1 enzymatic assay was developed using DAPI. The fluorescence assay was used for screening of polyP synthesis inhibitors. The assay will be useful in high-throughput screening of putative antivirulence molecules targeting enteric pathogens. Acknowledgments
