- Therefore, bacterial cell walls deserve special attention because they (i) provide the essential structure for bacterial viability by protecting against the often hostile environment, (ii) are composed of unique components found nowhere else in nature, (iii) are responsible for the shape of the bacteria, (iv) provide a halt for ligands and proteins for adherence to host cells, (v) expose receptor sites for drugs or viruses, (vi) represent the most important sites for attack of antibiotics, (vii)...

Oct 3, 2016 · Bacteria are single-celled organisms and the cell wall that surrounds their plasma membrane, is made from a polymer (rather like a mesh) of amino acids and sugars. This wall is a crucial...

Jun 15, 2015 · Over 3 billion years ago, cellular life began anaerobically. A new study now establishes a key link between oxidative stress and proliferation of wall-less bacteria known as L-forms. The finding provides insights into both the origin of life and the potential threat posed by pathogenic L-forms.

Peptidoglycan (PG) is the major structural component of the cell wall in both Gram-positive and Gram-negative bacteria. Thus, much research in the bacterial morphology field focuses on defining the mechanisms by which the cell wall is synthesized and modified to produce different cell body shapes.
The peptidoglycan wall is a defining feature of bacterial cells and was probably already present in their last common ancestor. L-forms are bacterial variants that lack a cell wall and divide by a variety of processes involving membrane blebbing, tubulation, vesiculation and fission.
