ABSTRACT
Wall teichoic acid (WTA) was isolated from Enterococcus faecium strain U0317 and structurally characterized using (1)H, (13)C, and (31)P NMR spectroscopy, including two-dimensional COSY, TOCSY, ROESY, HMQC, and HMBC experiments. Further compositional determination was undertaken using classical chemical methods and HF treatment followed by GLC and GLC-MS analyses. The repeating unit of WTA consisted of two residues of 2-acetamido-2-deoxy-D-galactose, glycerol (Gro), and phosphate, and has the structure shown below [See formula in text].
