WebFeb 23, 2016 · The envelope of Gram-negative bacteria is essential for viability. First, it includes the cell wall, a continuous polymer of peptidoglycan (PG) that determines cell morphology and protects against osmotic stress. Moreover, the envelope constitutes a protective barrier between the cell interior and t …
WebAn imbalance in the metabolism of peptidoglycan can lead to a rapid loss of cell wall integrity, followed by osmotic swelling and cell lysis. Such effects underpin the actions of cell wall–active antibiotics (described below) and the effect of lysozyme, an enzyme secreted by leukocytes as part of innate immunity.
