Bacterial Outer Membrane Proteins

Medical Definition: Proteins isolated from the outer membrane of Gram-negative bacteria.
Guide Notes: coord IM with specific protein (IM) + specific gram-negative bacterium (IM)
Also Called: Outer Membrane Lipoproteins, Bacterial
Previously Indexed: Bacterial Proteins (1966-1984),Membrane Proteins (1977-1984)
Bacterial Outer Membrane Proteins Categories.
Canadian Medical Guide Definition Adhesins, Bacterial - Cell-surface components or appendages of bacteria that facilitate adhesion (BACTERIAL ADHESION) to other cells or to inanimate surfaces. Most fimbriae (FIMBRIAE, BACTERIAL) of gram-negative bacteria function as adhesins, but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin. In gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin.
Canadian Medical Guide Definition Bacterial Transferrin Receptor Complex - A complex of proteins that forms a receptor for TRANSFERRIN in BACTERIA. Many pathogenic bacteria utilize the transferrin-binding complex to acquire their supply of iron from serum.
Canadian Medical Guide Definition Fimbriae Proteins - Proteins that are structural components of bacterial fimbriae (FIMBRIAE, BACTERIAL) or sex pili (PILI, SEX).
Canadian Medical Guide Definition Porins - Protein molecules situated in the outer membrane of gram-negative bacteria that, in dimeric or trimeric form, constitute a water-filled transmembrane channel allowing passage of ions and other small molecules. Porins are also found in bacterial cell walls, and in plant, fungal, mammalian and other vertebrate cell and mitochondrial membranes.
