GO
GO:0001530 Binding to a lipopolysaccharide. GO:0042597 The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria). GO:0015920 The directed movement of lipopolysaccharides into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. A lipopolysaccharide is any of a group of related, structurally complex components of the outer membrane of Gram-negative bacteria. Lipopolysaccharides consist three covalently linked regions, lipid A, core oligosaccharide, and an O side chain. Lipid A is responsible for the toxicity of the lipopolysaccharide.
