Bacterial cell wall synthesis: new insights from localization studies.
In order to maintain shape and withstand intracellular pressure, most bacteria are surrounded by a cell wall that consists mainly of the cross-linked polymer peptidoglycan (PG). The importance of PG for the maintenance of bacterial cell shape is underscored by the fact that, for various bacteria, several mutations affecting PG synthesis are associated with cell shape defects. In recent years, t...
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 کاملStudies on the Chemical Structure of the Streptococcal Cell Wall
The trypsinized cell walls of Group C streptococci contain two components, the group-specific carbohydrate and a mucopeptide polymer. Hot formamide extraction of Group C cell walls results in a soluble group-specific carbohydrate fraction and an insoluble mucopeptide residue. This mucopeptide, similar in composition to that of Groups A and A-variant streptococci, contains N-acetylglucosamine, N...
متن کاملBacterial cell wall composition and the influence of antibiotics by cell-wall and whole-cell NMR.
The ability to characterize bacterial cell-wall composition and structure is crucial to understanding the function of the bacterial cell wall, determining drug modes of action and developing new-generation therapeutics. Solid-state NMR has emerged as a powerful tool to quantify chemical composition and to map cell-wall architecture in bacteria and plants, even in the context of unperturbed inta...
متن کاملStudies on the Antigenic Substance of the Bacterial Cell
Putting together the results of such experiments as those outlined above, we can set down the following definite facts. 1. The substance of the bacterial cell can be roughly divided into two antigenic entities. One of these is the so called "nucleoprotein" substance, the other the residue substance or soluble material of Dochez and Avery and Avery and Heidelberger, both of which have been repea...
