| molecular function |
|---|
| | GO:0005524 | | ATP binding | | Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| | GO:0015078 | | hydrogen ion transmembrane transporter activity | | Enables the transfer of hydrogen ions from one side of a membrane to the other. |
| | GO:0000166 | | nucleotide binding | | Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose. |
| | 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: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: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. |
| cellular component |
|---|
| | 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:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0033180 | | proton-transporting V-type ATPase, V1 domain | | A protein complex that forms part of a proton-transporting V-type ATPase and catalyzes ATP hydrolysis. The V1 complex consists of: (1) a globular headpiece with three alternating copies of subunits A and B that form a ring, (2) a central rotational stalk composed of single copies of subunits D and F, and (3) a peripheral stalk made of subunits C, E, G and H. Subunits A and B mediate the hydrolysis of ATP at three reaction sites associated with subunit A. |
| | GO:0005774 | | vacuolar membrane | | The lipid bilayer surrounding the vacuole and separating its contents from the cytoplasm of the cell. |
| | GO:0000221 | | vacuolar proton-transporting V-type ATPase, V1 domain | | The V1 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. |
