FLAG epitope tagged HdrR was directly purified from S. mutans strains either (A) encoding or (B) lacking hdrM and then subjected to electrospray ionization mass spectrometry as described in Experimental Procedures. Mass spectra of 350 – 2000 m/z were collected and then deconvolved with Protein Deconvolution 4.0 software.
