GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. GO:0045259 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. GO:0030257 A complex of approximately 20 proteins, most of which are located in the cytoplasmic membrane that carries out protein secretion in the bacterial type III secretion system; type III secretion also requires a cytoplasmic, probably membrane-associated ATPase. GO:0005524 Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. GO:0016887 Catalysis of the reaction: ATP + H2O = ADP + H+ phosphate. ATP hydrolysis is used in some reactions as an energy source, for example to catalyze a reaction or drive transport against a concentration gradient. GO:0044780 The assembly of a bacterial-type flagellum, a motor complex composed of an extracellular helical protein filament coupled to a rotary motor embedded in the cell envelope which functions in cell motility.

  • GO:0030254 The process in which proteins are transferred into the extracellular milieu or directly into host cells by the bacterial type III secretion system; secretion occurs in a continuous process without the distinct presence of periplasmic intermediates and does not involve proteolytic processing of secreted proteins.
  • GO:0015986 The chemical reactions and pathways resulting in the formation of ATP driven by transport of protons across a membrane to generate an electrochemical gradient (proton-motive force).
  • GO:1902600 The directed movement of a proton across a membrane.
  • GO:0009058 A cellular process consisting of the biochemical pathways by which a living organism synthesizes chemical substances. This typically represents the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones.
