title: Core oligosaccharide of Escherichia coli B-the structure required for bacteriophage T4 recognition.
abstract: The structure of Escherichia coli B strain PCM 1935 core oligosaccharide has been investigated by (1)H and (13)C NMR spectroscopy, MALDI-TOF MS and ESI MS(n). It was concluded that the core oligosaccharide is a pentasaccharide with the following structure: ESI MS/MS analysis revealed that the glycine (a minor component) is linked to the →3,7)-l-α-d-Hepp-(1→ residue.
