SPOR-RlpA binding to PG derivatives. Representative extracted-ion chromatograms of the non-denaturing mass spectrometry results displaying the SPOR-RlpA domain as an intact monomer and in complex with distinct authentic synthetic muropeptides. a SPOR-RlpA domain alone (20 μM) and the 20 μM domain plus 500 μM of (b) 1, (c) 2, (d) 3, (e) 4, and (f) 5. The intensity of the signal (Y axis) is plotted vs Mw (average molecular weight) of the indicated species. Masses for the different compounds are as follows: 988.4 Da (compound 1), 986.4 (compound 2), 956.4 (compound 3), 1944.7 (compound 4) and 2016.9 (compound 5).
