T cell epitopes are mostly nonmodified peptides, although posttranslationally modified peptide epitopes have been described, but they originated from viral or self-proteins. In this study, we provide evidence of a bacterial methylated T cell peptide epitope. The mycobacterial heparin-binding hemagglutinin (HBHA) is a protein Ag with a complex C-terminal methylation pattern and is recognized by T cells from humans latently infected with Mycobacterium tuberculosis By comparing native HBHA with recombinant HBHA produced in Mycobacte
