|
ATP binding
|
Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
GO:0015991
|
ATP hydrolysis coupled proton transport
|
The transport of protons against an electrochemical gradient, using energy from ATP hydrolysis. |
GO:0016820
|
hydrolase activity, acting on acid anhydrides, catalyzing transmembrane movement of substances
|
Catalysis of the hydrolysis of an acid anhydride to directly drive the transport of a substance across a membrane. |
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. |
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:0046034
|
ATP metabolic process
|
The chemical reactions and pathways involving ATP, adenosine triphosphate, a universally important coenzyme and enzyme regulator. |
GO:0033178
|
proton-transporting two-sector ATPase complex, catalytic domain
|
A protein complex that forms part of a proton-transporting two-sector ATPase complex and catalyzes ATP hydrolysis or synthesis. The catalytic domain (F1, V1, or A1) comprises a hexameric catalytic core and a central stalk, and is peripherally associated with the membrane when the two-sector ATPase is assembled. |
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. |
