Common NameGlucosyl-heptosyl3-KDO2-lipid A-bisphosphate
DescriptionGlucosyl-heptosyl3-kdo2-lipid a-bisphosphate is a component of LPS. Bacterial lipopolysaccharides (LPS) typically consist of a hydrophobic domain inserted into the outer membrane known as lipid A (or endotoxin), a phosphorylated "core" oligosaccharide and a distal polysaccharide (or O antigen). The core oligosaccharides are conceptually divided into two regions: inner core and outer core. The inner core is highly conserved, comprises three deoxy-D-manno-octulosonic acid (KDO) and L-glycero-D-manno-heptose (Hep) and is often phosphorylated. The inner core oligosaccharide plays a critical role in essential barrier function of the outer membrane. The outer core comprises a tri-hexose backbone modified with varying side-branch substitutions of hexose and acetamidohexose residues. The outer core provides an attachment site for O-antigen. The completed lipid A-KDO2 serves as the acceptor on which the core oligosaccharide chains are assembled by sequential glycosyl transfer from nucleotide sugar precursors. This process involves a co-ordinated complex of membrane-associated glycosyltransferases acting at the cytoplasmic face of the plasma membrane.
