  • Title: The glycerol teichoic acid from walls of Staphylococcus epidermidis I2.
    Author: Archibald AR, Baddiley J, Shaukat GA.
    Journal: Biochem J; 1968 Dec; 110(3):583-8. PubMed ID: 5701689.
    Abstract:
    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 and d-alanyl ester substituents. 3. 2-O-beta-d-Glucopyranosylglycerol was isolated and characterized as its crystalline hexa-O-acetate. 4. Unlike that of certain other bacteria, the peptidoglycan component of the wall is not solubilized by NN-dimethylhydrazine. 5. The membrane teichoic acid is also a (1-->3)-linked poly(glycerol phosphate) but contains a smaller proportion of glucosyl substituents.
