Regulation of bacterial cell wall growth.
During growth and propagation, a bacterial cell enlarges and subsequently divides its peptidoglycan (PG) sacculus, a continuous mesh-like layer that encases the cell membrane to confer mechanical strength and morphological robustness. The mechanism of sacculus growth, how it is regulated and how it is coordinated with other cellular processes is poorly understood. In this article, we will discu...
متن کاملBacterial Cell Wall-induced Immunosuppression
Asingle intraperitoneal injection of bacterial cell walls derived from groupA streptococci (SCW)' into susceptible rats results in the development of acute and chronic erosive polyarthritis (1, 2) . The pathology of the lesion leading to joint destruction has been shown to be aT cell-dependent, cell-mediated response to the deposition of the group A streptococcal peptidoglycan-polysaccharide po...
متن کاملRegulation of bacterial cell walls: correlation between autolytic activity and cell wall turnover in Staphylococcus aureus.
Cell wall turnover was examined in parent and mutant strains of Staphylococcus aureus. Peptidoglycan and teichoic acid were observed to undergo turnover in the wild-type strain during exponential growth; however, the rate of turnover did not decrease when the growth rate slowed, as the culture entered stationary phase. Isolated native cell walls and crude soluble autolytic enzyme were prepared ...
متن کاملTurnover of bacterial cell wall peptidoglycans.
The cell wall peptidoglycan of LactobaciZZus acido$hiZus strain 63 AM Gasser has been shown to turn over rapidly during balanced exponential growth and recovery from amino acid deprivation. In contrast, turnover of either pulselabeled or extensively labeled peptidoglycan of Streptococcus fuecalis ATCC 9790 was not detected by the same method and experimental conditions. In S. faecalis, peptidog...
متن کاملRegulation of the bacterial cell wall: effect of antibiotics on lipid biosynthesis.
Antibiotics that inhibit the biosynthesis of the cell wall, such as vancomycin, penicillin, d-cycloserine, and bacitracin, stimulate the incorporation of lysine into lipids that are extractable with n-butanol-6 M pyridinium acetate. Approximately 93% of this lysine is in lysylphosphatidylglycerol (LPG). The remaining lysine is incorporated in another as yet uncharacterized lipid. Because the ly...
