Metabolic anticipation in Mycobacterium tuberculosis

Abstract

Humans serve as both host and reservoir for Mycobacterium tuberculosis, making tuberculosis a theoretically eradicable disease. How M. tuberculosis alternates between host-imposed quiescence and sporadic bouts of replication to complete its life cycle, however, remains unknown. Here, we identify a metabolic adaptation that is triggered upon entry into hypoxia-induced quiescence but facilitates subsequent cell cycle re-entry. Catabolic remodelling of the cell surface trehalose mycolates of M. tuberculosis specifically generates metabolic intermediates reserved for re-initiation of peptidoglycan biosynthesis. These adaptations reveal a metabolic network with the regulatory capacity to mount an anticipatory response.

Bacterial Cell Wall Structure (ASM)

Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Here is the latest research on bacterial cell wall structures.
