Mycobacterium tuberculosis (Mtb) causes tuberculosis, one of the leading causes of fatal infectious diseases worldwide. Cell-cell recognition between the pathogen Mtb and its host is mediated in part by glycosylated proteins. So far, glycoproteins in Mtb are understudied and for only very few glycoproteins glycosylation sites have been described, e.g., alanine and proline rich secreted protein apa, superoxide dismutase SODC, lipoprotein lpqH and MPB83/MPT83. In this study, glycosylated proteins in Mtb culture filtrate were investigated using liquid chromatography-mass spectrometry approaches and bioinformatic analyses. To validate the presence of glycoproteins, several strategies were pursued including collision induced dissociation, high energy collision dissociation and electron transfer dissociation techniques, and bioinformatics analyses involving a neutral loss search for glycosylated moieties. After extensive data curation, we report glycosylation sites for thirteen Mtb glycoproteins using a combination of mass spectrometry techniques on a dataset collected from culture filtrate proteins. This is the first glycoproteomics study identifying glycosylation sites on mycobacterial culture filtrate proteins (CFP) on a global scale.
