LTA inhibition of heparin binding of HlpA. Low-molecular-mass profiles of heparin-binding proteins from a total S. gallolyticus cell extract or that of purified HlpA-His were generated by mass spectrometry. Bars represent the peak intensities of HlpA (m/z 9,707) and HlpA-His (m/z 10,530) that were retained by immobilized heparin after preincubation or postincubation with 25 or 50 μg/μl soluble LTA. Error bars indicate the standard errors from three replicate experiments.
