| | GO:0046961 | | proton-transporting ATPase activity, rotational mechanism | | Catalysis of the transfer of protons from one side of a membrane to the other according to the reaction: ATP + H2O + H+(in) = ADP + phosphate + H+(out), by a rotational mechanism. |
| biological process |
|---|
| | GO:0015991 | | ATP hydrolysis coupled proton transport | | The transport of protons against an electrochemical gradient, using energy from ATP hydrolysis. |
| | GO:0015986 | | ATP synthesis coupled proton transport | | The transport of protons across a membrane to generate an electrochemical gradient (proton-motive force) that powers ATP synthesis. |
| | GO:0016049 | | cell growth | | The process in which a cell irreversibly increases in size over time by accretion and biosynthetic production of matter similar to that already present. |
| | GO:0006811 | | ion transport | | The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| | GO:0006797 | | polyphosphate metabolic process | | The chemical reactions and pathways involving a polyphosphate, the anion or salt of polyphosphoric acid. |
| | GO:0006461 | | protein complex assembly | | The aggregation, arrangement and bonding together of a set of components to form a protein complex. |
| | GO:0015992 | | proton transport | | The directed movement of protons (hydrogen ions) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| | GO:0006810 | | transport | | The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein. |
| | GO:0007035 | | vacuolar acidification | | Any process that reduces the pH of the vacuole, measured by the concentration of the hydrogen ion. |
| | GO:0070072 | | vacuolar proton-transporting V-type ATPase complex assembly | | The aggregation, arrangement and bonding together of a vacuolar proton-transporting V-type ATPase complex, proton-transporting two-sector ATPase complex that couples ATP hydrolysis to the transport of protons across the vacuolar membrane. |
| cellular component |
|---|
| | GO:0000324 | | fungal-type vacuole | | A vacuole that has both lytic and storage functions. The fungal vacuole is a large, membrane-bounded organelle that functions as a reservoir for the storage of small molecules (including polyphosphate, amino acids, several divalent cations (e.g. calcium), other ions, and other small molecules) as well as being the primary compartment for degradation. It is an acidic compartment, containing an ensemble of acid hydrolases. At least in S. cerevisiae, there are indications that the morphology of the vacuole is variable and correlated with the cell cycle, with logarithmically growing cells having a multilobed, reticulated vacuole, while stationary phase cells contain a single large structure. |
| | GO:0000329 | | fungal-type vacuole membrane | | The lipid bilayer surrounding a vacuole, the shape of which correlates with cell cycle phase. The membrane separates its contents from the cytoplasm of the cell. An example of this structure is found in Saccharomyces cerevisiae. |
| | GO:0016021 | | integral component of membrane | | The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0033179 | | proton-transporting V-type ATPase, V0 domain | | A protein complex that forms part of a proton-transporting V-type ATPase and mediates proton transport across a membrane. The V0 complex consists of at least four different subunits (a,c,d and e); six or more c subunits form a proton-binding rotor ring. |
| | GO:0005774 | | vacuolar membrane | | The lipid bilayer surrounding the vacuole and separating its contents from the cytoplasm of the cell. |
| | GO:0000220 | | vacuolar proton-transporting V-type ATPase, V0 domain | | The V0 domain of a proton-transporting V-type ATPase found in the vacuolar membrane. |
| | GO:0005773 | | vacuole | | A closed structure, found only in eukaryotic cells, that is completely surrounded by unit membrane and contains liquid material. Cells contain one or several vacuoles, that may have different functions from each other. Vacuoles have a diverse array of functions. They can act as a storage organelle for nutrients or waste products, as a degradative compartment, as a cost-effective way of increasing cell size, and as a homeostatic regulator controlling both turgor pressure and pH of the cytosol. |
