Mass spectrometry data, carbohydrate composition of the WTA repeating units, and WGA binding properties for the bacterial strains used in this study.

1Gal, galactose; Glc, glucose; GlcNAc, N-acetylglucosamine; Rbo, ribitol; Rha, rhamnose; in serovar 4b strain WSLC 1042, GlcNAc is incorporated in the polyribitol-phosphate chain and decorated with Gal and Glc residues.2The calculated masses correspond to the monomeric unit of WTA, i.e., ribitol and attached carbohydrates.3WTAs of strains EGDe and WSLC 1485 were detected as protonated molecules, whereas WTA samples of strains WSLC 1442 and WSLC 1042 were identified as lithiated molecules.4+, binding; −, no binding; WGA: wheat germ agglutinin.5L. monocytogenes strain WSLC 1442 is a GlcNAc-negative serovar 1/2a mutant strain [27].
