Located in the outer membrane of the cell 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, with the bulk of the gene product located on the side opposite to the side that faces the periplasm. Loosely bound to the surface of the outer membrane of the cell that faces away from the cytoplasm, but not integrated into the hydrophobic region. The side of the outer membrane that is opposite to the side that faces the periplasm of the 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. A structure that lies outside the plasma membrane and surrounds the entire cell. 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. Any constituent part of a membrane, a 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.
