Detailed analysis of the S. acidocaldarius Δagl16 mutant background S-layer glycopeptide. The total ion chromatograms of the glycan profiles for the tryptic peptides T24 (A) and T26 (B) are shown. The annotated peaks show that the truncated Hex₂QuiS₁HexNAc₂ glycoform is present on the observed glycopeptides, whereas the full glycan is missing. For reference, a cartoon depicting the full glycan is provided for each spectrum. Glycan symbols: blue sphere, glucose; green sphere, mannose; orange sphere, sulfoquinovose; blue square, GlcNAc.
