 · Localization of Other Proteins Involved in Bacterial Cell Wall Synthesis The cell walls of gram-positive bacteria contain proteins as well as charged polymers such as teichoic and teichuronic acids which are covalently linked to PG (57, ). As with PG, the teichoic acid (TA) is synthesized as a lipid-linked precursor in the webarchive.icu by: 26/05/ · The biosynthesis of bacterial cell wall peptidoglycan is a complex process that involves enzyme reactions that take place in the cytoplasm and on the inner side and outer side of the cytoplasmic membrane. This review deals with the cytoplasmic steps of peptidoglycan biosynthesis, which can be divided into four sets of reactions that lead to the syntheses of (1) UDP-N-acetylglucosamine from. 1.

SUMMARY 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.
