title: Structure of the O-polysaccharide of Photorhabdus luminescens subsp. laumondii containing D-glycero-D-manno-heptose and 3,6-dideoxy-3-formamido-D-glucose.
abstract: The O-polysaccharide from the lipopolysaccharide of a symbiotic bacterium Photorhabdus luminescens subsp. laumondii TT01 from an insect-pathogenic nematode was studied by sugar analysis and (1)H and (13)C NMR spectroscopy and found to contain D-glycero-D-manno-heptose (DDHep) and 3,6-dideoxy-3-formamido-D-glucose (D-Qui3NFo). The following structure of the pentasaccharide repeating unit of the O-polysaccharide was established:
