The glycerol teichoic acid of walls of Staphylococcus lactis I3.
1. The teichoic acid from walls of Staphylococcus lactis I3 was isolated by extraction with trichloroacetic acid and shown to contain glycerol, N-acetylglucosamine, phosphate and d-alanine in the molecular proportions 1:1:2:1. The alanine is attached to the polymer through ester linkages. 2. Hydrolysis with acid gave alanine, glucosamine and glycerol diphosphates. Under mild acid conditions a r...
متن کاملThe glycerol teichoic acid from walls of Staphylococcus epidermidis I2.
1. Walls of Staphylococcus epidermidis I2 contain 30% (w/w) of a glycerol teichoic acid containing phosphate, d-alanine and d-glucose in the molecular proportions 1:0.25:0.50. 2. The teichoic acid was isolated by extraction with trichloroacetic acid and with dilute aqueous NN-dimethylhydrazine at pH7, and was shown to be a (1-->3)-linked poly(glycerol phosphate) containing beta-d-glucopyranosyl...
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 کاملWall Teichoic Acid Glycosylation Governs Staphylococcus aureus Nasal Colonization
UNLABELLED Nasal colonization by the human pathogen Staphylococcus aureus is a major risk factor for hospital- and community-acquired infections. A key factor required for nasal colonization is a cell surface-exposed zwitterionic glycopolymer, termed wall teichoic acid (WTA). However, the precise mechanisms that govern WTA-mediated nasal colonization have remained elusive. Here, we report that ...
متن کاملThe glycerol teichoic acid from the walls of Staphylococcus albus N.T.C.C. 7944.
The teichoic acids in and beneath the walls of staphylococci are particularly interesting, not only with regard to structure and function but also because of their serological properties. The groupantigenic polysaceharide A from Staphylococcus aureus is indistinguishable from the wall teichoic acid from that organism, and a similar preparation from S. albi4s strains is serologically indistingui...
