Identification
Name: Lipid A-core
Description:Lipid a-core belongs to the class of Polyhexoses. These are polysaccharides in which the saccharide units are hexoses. (inferred from compound structure) Lipopolysaccharide (LPS) is a major component on the surface of Gram negative bacteria and is composed of lipid A-core and the O antigen polysaccharide. (PMID 20333251) WaaL is a membrane enzyme implicated in ligating undecaprenyl-diphosphate (Und-PP)-linked O antigen to lipid A-core oligosaccharide. (PMID 19019161) MsbA is an essential ATP-binding cassette half-transporter in the cytoplasmic membrane of the gram-negative Pseudomonas aeruginosa and is required for the export of lipopolysaccharides (LPS) to the outer membrane, most likely by transporting the lipid A core moiety.
