physiological function | the enzyme EptC serves a dual role in modifying the flagellar rod protein, FlgG, and the lipid A domain lipooligosaccharide with a pEtN residue. The enzyme also catalyzes the addition of phosphoethanolamine to the first heptose sugar of the inner core oligosaccharide of lipooligosaccharide, a fourth enzymatic target. Modification of Campylobacter jejuni lipid A with phosphoethanolamine results in increased recognition by the human Toll-like receptor 4-myeloid differentiation factor 2 complex, along with providing resistance to relevant mammalian and avian antimicrobial peptides (i.e., defensins). Modification of surface structures with phosphoethanolamine by EptC is key to its ability to promote commensalism in an avian host and to survive in the mammalian gastrointestinal environment. Modification of FlgG is required for efficient flagellar production and motility | Campylobacter jejuni |
