• Comparative proteomic analyses across different Mtb strains.
• Integration of machine learning and bioinformatics for protein function and drug resistance prediction.

Main Results:

• Refined genome annotations and identification of novel protein-coding regions.
• Detailed profiling of proteins in distinct cellular compartments (cell wall, membranes, cytoplasm).
• Uncovered unique protein variants and conserved elements linked to bacterial adaptation and virulence.
• Mapped protein interaction networks revealing essential metabolic and survival pathways.
• Predicted protein functions, post-translational modifications, and contributions to drug resistance.

Conclusions:

• Modern proteomic and bioinformatics approaches provide a dynamic portrait of the Mtb proteome.
• These strategies facilitate the discovery of novel biomarkers, drug targets, and vaccine candidates.
• The comprehensive Mtb proteome knowledge is vital for developing improved diagnostics and effective tuberculosis treatments.
