TABLE 4.

Placement of individual (acetylated and unsubstituted) monosaccharide residues in the oligosaccharide sequence of LMM R7A EPS (also refer to structure in Fig. 9)

Numbers in parentheses indicate a position of O-acetyl substituent on glycosyl residue; (0) indicates non-O-acetylated residue; subscript number indicates position of O-acetyl group in glycosyl residue, i.e. A₃ indicates mono-3-O-acetylated β-RibfA; A_2,3 indicates 2,3-di-O-acetylated β-RibfA; ′, i.e. E, E′, E″, E‴, E2, E2′, or D3, D3′, D3″, indicates different variants of same monosaccharide residue observed in NMR experiments due to different substitution patterns by O-acetyl groups on neighboring residues.
