| GO:0005575 | cellular_component | A location, relative to cellular compartments and structures, occupied by a macromolecular machine. There are three types of cellular components described in the gene ontology: (1) the cellular anatomical entity where a gene product carries out a molecular function (e.g., plasma membrane, cytoskeleton) or membrane-enclosed compartments (e.g., mitochondrion); (2) virion components, where viral proteins act, and (3) the stable macromolecular complexes of which gene product are parts (e.g., the clathrin complex). |
| GO:0110165 | cellular anatomical structure | A part of a cellular organism consisting of a material entity with granularity above the level of a protein complex but below that of an anatomical system. Note that cellular organisms exclude viruses. |
| GO:0071944 | cell periphery | The broad region around and including the plasma membrane of a cell, encompassing the cell cortex (inside the cell), the plasma membrane, and any external encapsulating structures. |
| GO:0016020 | membrane | A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. |
| GO:0019867 | outer membrane | The external membrane of Gram-negative bacteria or certain organelles such as mitochondria and chloroplasts; freely permeable to most ions and metabolites. |
| GO:0030312 | external encapsulating structure | A structure that lies outside the plasma membrane and surrounds the entire cell or cells. This does not include the periplasmic space. |
| GO:0019898 | extrinsic component of membrane | The component of a membrane consisting of gene products and protein complexes that are loosely bound to one of its surfaces, but not integrated into the hydrophobic region. |
| GO:0098552 | side of membrane | A cellular component consisting of one leaflet of a membrane bilayer and any proteins embedded or anchored in it or attached to its surface. |
| GO:0030313 | cell envelope | 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. |
| GO:0009279 | cell outer membrane | A lipid bilayer that forms the outermost membrane of the cell envelope; enriched in polysaccharide and protein; the outer leaflet of the membrane contains specific lipopolysaccharide structures. |
| GO:0031240 | external side of cell outer membrane | The side of the outer membrane that is opposite to the side that faces the periplasm of the cell. |
| GO:0031242 | extrinsic component of external side of cell outer membrane | The component of a cell outer membrane consisting of gene products and protein complexes that are loosely bound to its external surface, but not integrated into the hydrophobic region. |
| GO:0031244 | extrinsic component of cell outer membrane | The component of the cell outer membrane consisting of gene products and protein complexes that are loosely bound to one of its surfaces, but not integrated into the hydrophobic region. |
