Schematic diagram of the glycan phenotypes described in Table 1. The wild type and knockout mutant repeat unit phenotypes (P1 to P6) are shown to highlight the loss of specific residues from the wild-type structure as a result of gene mutations. In the glycan structure, shading represents CPS sugar residues that form the repeat unit and clear ovals are non-sugar modifications. OMePN, phosphoramidate; NGro, N-glycerol; Rib, ribose; GalfNAc, N-acetylgalactosamine in the furanose configuration; GlcA, glucuronic acid; 6-OMe, 6-O-Methyl; Hep, heptose, 3-OMe, 3-O-methyl.
