PW002059Metabolicpeptidoglycan biosynthesis I 2Peptidoglycan is a net-like polymer which surrounds the cytoplasmic membrane of most bacteria and functions to maintain cell shape and prevent rupture due to the internal turgor.In E. coli K-12, the peptidoglycan consists of glycan strands of alternating subunits of N-acetylglucosamine (GlcNAc) and N-acetylmuramic acid (MurNAc) which are cross-linked by short peptides.

The preferred osmoprotectant of E. coli is glycine betaine. However, its synthesis relies on an external supply of proline, betaines, or choline. When these compounds are not available, a cell can achieve a moderate level of osmotic tolerance by accumulation of glutamate and trehalose.
E. coli synthesizes and accumulates trehalose when exposed to osmotic stress and low temperatures. It is synthesized from UDP-glucose and glucose-6-phosphate via trehalose-6-phosphate, by the action of two enzymes, trehalose-6-phosphate synthase and trehalose-6-phosphate phosphatase. Expression of both genes encoding the two enzymes, otsA and otsB, is osmotically regulated. Transcription from these genes increases during osmotic stress and cold shock and when the cells enter stationary phase, and requires the stress sigma factor RpoS. Synthesis of trehalose is also stimulated directly by K+ ion-dependent activation of trehalose-6-phosphate synthase enzyme.
Under osmotic stress, E. coli overproduces trehalose, some of which is excreted to the periplasmic space. Once there, it is degraded by the periplasmic trehalase. This process was named "a futile cycle for controlling the cytoplasmic level of trehalose".
