A protein complex which is capable of catalytic activity. |
|
GO:0032991
|
protein-containing complex
|
A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together. |

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:0098796
|
membrane protein complex
|
Any protein complex that is part of a membrane. |
|
GO:0016020
|
membrane
|
A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. |
|
GO:1990351
|
transporter complex
|
A protein complex facilitating transport of molecules (proteins, small molecules, nucleic acids) into, out of or within a cell, or between cells. |
|
GO:1902495
|
transmembrane transporter complex
|
A transmembrane protein complex which enables the transfer of a substance from one side of a membrane to the other. |
|
GO:0016469
|
proton-transporting two-sector ATPase complex
|
A large protein complex that catalyzes the synthesis or hydrolysis of ATP by a rotational mechanism, coupled to the transport of protons across a membrane. The complex comprises a membrane sector (F0, V0, or A0) that carries out proton transport and a cytoplasmic compartment sector (F1, V1, or A1) that catalyzes ATP synthesis or hydrolysis. Two major types have been characterized: V-type ATPases couple ATP hydrolysis to the transport of protons across a concentration gradient, whereas F-type ATPases, also known as ATP synthases, normally run in the reverse direction to utilize energy from a proton concentration or electrochemical gradient to synthesize ATP. A third type, A-type ATPases have been found in archaea, and are closely related to eukaryotic V-type ATPases but are reversible. |

GO:0034703
|
cation channel complex
|
An ion channel complex through which cations pass. |
|
GO:0034702
|
monoatomic ion channel complex
|
A protein complex that spans a membrane and forms a water-filled channel across the phospholipid bilayer allowing selective monoatomic ion transport down its electrochemical gradient. |
|
GO:0098803
|
respiratory chain complex
|
Any protein complex that is part of a respiratory chain. |
|
GO:0045259
|
proton-transporting ATP synthase complex
|
A proton-transporting two-sector ATPase complex that catalyzes the phosphorylation of ADP to ATP during oxidative phosphorylation. The complex comprises a membrane sector (F0) that carries out proton transport and a cytoplasmic compartment sector (F1) that catalyzes ATP synthesis by a rotational mechanism; the extramembrane sector (containing 3 a and 3 b subunits) is connected via the d-subunit to the membrane sector by several smaller subunits. Within this complex, the g and e subunits and the 9-12 c subunits rotate by consecutive 120 degree angles and perform parts of ATP synthesis. This movement is driven by the hydrogen ion electrochemical potential gradient. |
