GO:0043234
|
protein complex
|
A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical. |
GO:1902494
|
catalytic complex
|
A protein complex which is capable of catalytic activity. |
GO:0044464
|
cell part
|
Any constituent part of a cell, the basic structural and functional unit of all organisms. |
GO:0032991
|
macromolecular complex
|
A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which the constituent parts function together. |
GO:0005575
|
cellular_component
|
The part of a cell or its extracellular environment in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together. |
GO:0005623
|
cell
|
The basic structural and functional unit of all organisms. Includes the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope. |
GO:1990204
|
oxidoreductase complex
|
Any protein complex that possesses oxidoreductase activity. |
GO:0009325
|
nitrate reductase complex
|
An enzyme complex that catalyzes the formation of nitrate from nitrite with the concomitant reduction of an acceptor. |
