bacteria; biogenesis; cell growth; cell membranes; cell walls; crosslinking; glycopeptides; glycosyltransferases; lipids; peptidoglycans; polymerization; polymers; sporulation
Abstract:
... The peptidoglycan (PG) cell wall is an extra-cytoplasmic glycopeptide polymeric structure that protects bacteria from osmotic lysis and determines cellular shape. Since the cell wall surrounds the cytoplasmic membrane, bacteria must add new material to the PG matrix during cell elongation and division. The lipid-linked precursor for PG biogenesis, Lipid II, is synthesized in the inner leaflet of t ...
