Wall Teichoic Acid Glycosylation
The biosynthetic enzymes involved in wall teichoic acid biogenesis in Grampositive bacteria have been the subject of renewed investigation in recent years with the benefit of modem tools of biochemistry and genetics. Nevertheless, there have been only limited investigations into the enzymes that glycosylate wall teichoic acid. Decades-old experiments in the model Gram-positive bacterium, Bacill...
متن کاملWall teichoic Acid-dependent adsorption of staphylococcal siphovirus and myovirus.
The molecular interactions between staphylococcal phages and host cell surfaces are poorly understood. Employing Staphylococcus aureus teichoic acid mutants, we demonstrate that wall teichoic acid (WTA), but not lipoteichoic acid, serves as a receptor for staphylococcal siphovirus and myovirus, while only the siphovirus requires glycosylated WTA.
متن کاملBiosynthesis of the wall teichoic acid in Bacillus licheniformis.
1. The biosynthesis of the wall teichoic acid, poly(glycerol phosphate glucose), has been studied with a particulate membrane preparation from Bacillus licheniformis A.T.C.C. 9945. The precursor CDP-glycerol supplies glycerol phosphate residues, whereas UDP-glucose supplies only glucose to the repeating structure of the polymer. 2. Synthesis proceeds through polyprenol phosphate derivatives, an...
متن کاملGlycosylation of wall teichoic acid in Staphylococcus aureus by TarM.
Wall teichoic acid (WTA) glycopolymers are major constituents of cell envelopes in Staphylococcus aureus and related gram-positive bacteria with important roles in cell wall maintenance, susceptibility to antimicrobial molecules, biofilm formation, and host interaction. Most S. aureus strains express polyribitol phosphate WTA substituted with D-alanine and N-acetylglucosamine (GlcNAc). WTA suga...
متن کاملProton-Binding Capacity of Staphylococcus aureus Wall Teichoic Acid and Its Role in Controlling Autolysin Activity
Wall teichoic acid (WTA) or related polyanionic cell wall glycopolymers are produced by most gram-positive bacterial species and have been implicated in various cellular functions. WTA and the proton gradient across bacterial membranes are known to control the activity of autolysins but the molecular details of these interactions are poorly understood. We demonstrate that WTA contributes substa...
