Common NameKDO2-lipid A, cold adapted
DescriptionKDO2-lipid A, cold adapted is a constituent of LPS. Lipid A is the hydrophobic anchor of the outer membrane lipopolysaccharide of E. coli. Free lipid A does not exist as such in cells. It is normally found glycosylated with two KDO (3-deoxy-D-manno-octulosonic acid) residues and acylated with laurate and myristate residues. However if E. coli cells are subjected to cold shock or grown at low temperatures the laurate residue is replaced by palmitoleate. Myristate is subsequently added, resulting in a distinct cold adapted form of KDO2-lipid A.
