Figure 5. Glycosylation status of purified AniA-FLAG variants.

Figure 5

Extracted ion chromatograms corresponding to the un- (full) mono- (dashed) and di- (dotted) glycosylated versions of the Leu358-Lys387 tryptic peptide containing the AniA glycosylation sites: (A) wild type, (B) S373A, (C) S378A, (D) S373A, S378A, (E) S373A, S378A, S385P. Corresponding variant sequences are shown in Table S6. (F) Proportion of un- (white) mono- (gray) or di- (black) glycosylated versions of each variant shown in (A)–(E), as determined by integration of extracted ion chromatograms. Values are mean, error bars show s.e.m. *, P = 0.01 2-sided Mann-Whitney test.
