Purpose: Examination of the role the chlamydial protease-like activity factor targets has in altering protein expression and relative abundance of post translational modification by monitoring global glycopeptide changes. Methods: Hela 229 cells were infected with Chlamydia trachomatis L2 RST5 CPAF-sufficient strain and RST17 CPAF-deficient strain, enriched for glycopeptides and analyzed on a Thermo Scientific™ Orbitrap Fusion™ Lumos™ Tribrid™ mass spectrometer. Thermo Scientific™ Proteome Discoverer™ software with Byonic node was used for data analysis. Results: Overall we identified over 5000 unique intact glycopeptides translating into over 600 unique glycoproteins. Number of unique glycopeptides/glycoforms with levels greater than two-fold change were observed upon infection with Chlamydia trachomatis L2 RST5 CPAF-sufficient and -deficient strain
