    Lipopolysaccharides, from Klebsiella pneumoniae
    Activator
    Lipopolysaccharides, from Klebsiella, are lipopolysaccharide endotoxins. Lipopolysaccharides, from Klebsiella pneumoniae, consist of three parts: lipid A, core oligosaccharide, and O-specific antigen or O-side chain. In smooth LPS, the core region is divided into two areas: the inner core near the lipid A and the outer core that provides attachment sites for the O-antigen. In the lipopolysaccharide of Klebsiella pneumoniae, the l,d-HeppII at the O-3 position can be replaced by an α-d-galacturonic acid residue (α-d-GalpA). In most studied Enterobacteriaceae, the core LPS contains inner core phosphorylation modifications, but the core LPS of Klebsiella pneumoniae lacks this modification. The unique core structure plays an important role in the outer membrane permeability and pathogenesis of Klebsiella pneumoniae.

    Lipopolysaccharides, from S. enterica serotype typhimurium
    Activator
    Lipopolysaccharides, from S. enterica serotype typhimurium, are a kind of lipid-polysaccharide endotoxin. Smooth Gram-negative bacteria's lipopolysaccharides are made up of three components: lipid A, core oligosaccharide, and O antigen (OAg). The O antigen is a polymer of sugar repeat units (RUs); the Wzz protein regulates the length of the O antigen in lipopolysaccharides, and the number of RUs attached to lipid A is determined by the modal value set by the Wzz protein. S. enterica typhimurium has two Wzz proteins: WzzST (which makes the modal range of the O antigen between 16 and 35 RUs) and WzzfepE (which makes the modal value over 100 RUs). Mutating the genes corresponding to these two proteins causes the formation of short-chain O antigen chains and significantly reduces bacterial pathogenicity.
