WebAug 15, 2024 · Here we combined a transposon screen in Yersinia pseudotuberculosis with biochemical analyses and identified ADP-β-D-manno-heptose (ADP-Hep), which mediates type III secretion system-dependent NF-κB activation and cytokine expression. ADP-Hep, but not other heptose metabolites, could enter host cytosol to activate NF-κB. WebAbout This Pathway. ADP-D-glycero-β-D- manno -heptose is a precursor for the inner core lipopolysaccharide (LPS) [ Kneidinger02 ]. The genes encoding the enzymes involved in this pathway have been found in the genome of many important pathogens, including Escherichia coli K-12, Campylobacter jejuni jejuni NCTC 11168 = ATCC 700819, … fellowes exeter
