Glycopeptides, such as the antibiotic vancomycin,inhibit both transglycosylation and transpeptidationreactions during peptidoglycan assembly. They bind to the muropeptidesubunit as it is transferred out of the cell cytoplasm and inhibitsubsequent polymerization reactions. Vancomycin is not effectiveagainst Gram-negative bacteria because it cannot penetrate their outermembrane. However, it has become important in clinical usage fortreatment of infections by strains of that are resistant to virtually all other antibiotics (MRSA).

Peptidoglycan - eLS: Essential for Life Science
Two models of how peptidoglycan may be arranged in the bacterial cell wall. (a) In the classic horizontal (hoop) model, the polymerised glycan chains lie in the plane of the cell wall (transverse view, red arrow). A rod‐shaped cell is composed of numerous individual hoops side by side (Side view) that are linked to one another by peptide crosslinks (not shown). In this model, the hexagonal array of crosslinked peptidoglycan (shown in Figure b) lies flat and wraps around the surface of the bacterial cell. (b) In the proposed vertical (scaffold) model, the glycan chains extend up and out of the plane of the cell wall (transverse view, red arrow and blue spikes). A complete cell wall is composed of many chains facing outward (Side view, blue spikes) and linked to one another by peptide crosslinks (not shown). The easiest way to envision this model is to rotate the hexagonal array of crosslinked peptidoglycan shown in Figure b by 90°, and then picture the chains of white and blue rectangles (the glycan chains) extending upwards out of the page (e.g. outwards from the surface of a cell). In (b), the extended glycan chains are not drawn to the same scale as the bacterial cell; their extension is exaggerated to illustrate the difference between the horizontal and vertical models.

Themembranesof Archaea form bilayers functionally equivalent to bacterialmembranes,but archaeal lipids are saturated, branched, repeating isoprenoidsubunitsthat attach to glycerol via an ether linkage as opposed to the esterlinkagefound in glycerides of eukaryotic and bacterial membrane lipids (Figure21).

Bacteria can change the composition and perhaps the structure of their peptidoglycan, depending on growth conditions and in response to their environmental surroundings.
