Abstract
Comprehensive strategies for detecting and analyzing proteins in Mycobacterium tuberculosis (Mtb) integrate advanced experimental and computational approaches to deepen understanding of the bacterium's biology, pathogenesis, and mechanisms of drug resistance. Recent technological advances have refined genome annotations by identifying novel protein-coding regions and improving existing gene models. Utilizing diverse fractionation techniques combined with mass spectrometry, proteins localized to distinct cellular compartments, including the cell wall, membranes, and cytoplasm, can be profiled, providing critical insights into their spatial organization and functional roles. Comparative proteomic analyses across multiple Mtb strains have uncovered both unique protein variants and conserved elements, shedding light on bacterial adaptation and virulence strategies. Mapping protein interaction networks has revealed essential pathways governing metabolism and survival, highlighting the intricate coordination of proteins that underpin Mtb pathogenicity. Furthermore, the integration of machine learning and bioinformatics tools has significantly advanced the prediction of protein functions, posttranslational modifications, and contributions to drug resistance, thereby enabling the prioritization of promising targets for therapeutic intervention. Collectively, these modern methodologies offer a detailed and dynamic portrait of the Mtb proteome, facilitating the discovery of novel biomarkers, drug targets, and vaccine candidates. This comprehensive knowledge base is vital for guiding the development of improved diagnostic tools, effective treatments, and, ultimately, strategies to control and eradicate tuberculosis.
