title: Structure and gene cluster of the O-antigen of Escherichia coli O102.
abstract: The O-polysaccharide (O-antigen) of Escherichia coli O102 was studied by sugar analysis along with one- and two-dimensional (1)H and (13)C NMR spectroscopy. The following structure of the branched pentasaccharide repeating unit was established: [formula: see text]. The O-antigen gene cluster of E. coli O102 was sequenced. The gene functions were tentatively assigned by comparison with sequences in the available databases and found to be in full agreement with the E. coli O102 O-polysaccharide structure.
