Located in the cell outer membrane such that some covalently attached portion of the gene product, for example part of a peptide sequence or some other covalently attached moiety such as a GPI anchor, spans or is embedded in one or both leaflets of the membrane. Loosely bound to one surface of the outer membrane of the cell, but not integrated into the hydrophobic region. The side of the outer membrane that faces the periplasm of the cell. The side of the outer membrane that is opposite to the side that faces the periplasm of the cell. A structure that lies outside the plasma membrane and surrounds the entire cell. Double layer of lipid molecules that encloses all cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins. The external membrane of Gram-negative bacteria or certain organelles such as mitochondria and chloroplasts; freely permeable to most ions and metabolites. Any constituent part of a cell, the basic structural and functional unit of all organisms. An envelope that surrounds a bacterial cell and includes the cytoplasmic membrane and everything external, encompassing the periplasmic space, cell wall, and outer membrane if present. A lipid bilayer that forms the outermost layer of the cell envelope; enriched in polysaccharide and protein; the outer leaflet of the membrane contains specific lipopolysaccharide structures. Any constituent part of an external encapsulating structure, a structure that lies outside the plasma membrane and surrounds the entire cell. A multilayered structure surrounding all or part of a cell; encompasses one or more lipid bilayers, and may include a cell wall layer; also includes the space between layers.
