Learning metabolic lessons from the best tutor, Mycobacterium tuberculosis

Since the landmark publication of the genome of Mycobacterium tuberculosis in the late 90s’s, we have seen a significant increase in our understanding of M. tuberculosis metabolism. These recent findings often challenge textbook knowledge derived from studies with model bacteria. During this seminar I will illustrate key examples of these step-changes in our knowledge and how they were achieved. These include the discovery of enzymes and entire metabolic pathways, which were initially refractory to annotation. Also, we will highlight unique aspects of M. tuberculosis physiology that cannot be appreciated from genomics, transcriptomics and proteomics experiments. We will cover pathways involved in core metabolism, as well as plasma membrane and cell envelope remodelling.
