LPS-protein complex containing proteins of 15 kD, 17 kD and 19 kD was isolated from F. tularensis outer membrane by solving with sodium deoxycholate with the subsequent gel filtration on Sephacryl S-200. Protein of 17 kD constituted the main protein component of the complex. The LPS-protein ratio of this complex was 1:1. Proteins contained in LPS-protein complex have mainly the alpha-spiral structure. In the absence of detergent these proteins and LPS formed micelles with molecular weight exceeding 10(7) D. LPS-protein complex was shown to have a protective effect in mice infected with F. tularensis virulent strain 503.

UI MeSH Term Description Entries
D008070 Lipopolysaccharides Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed) Lipopolysaccharide,Lipoglycans
D008823 Micelles Particles consisting of aggregates of molecules held loosely together by secondary bonds. The surface of micelles are usually comprised of amphiphatic compounds that are oriented in a way that minimizes the energy of interaction between the micelle and its environment. Liquids that contain large numbers of suspended micelles are referred to as EMULSIONS. Micelle

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
