Enzyme classification and Gene Ontology terms linked to this protein.

13 GO

Gene Ontology (GO)

13
  • GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
  • 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:0140662 Binding to a protein or a protein-containing complex to assist the protein folding process, driven by ATP hydrolysis.
  • GO:0031072 Binding to a heat shock protein, a protein synthesized or activated in response to heat shock.
  • GO:0044183 Binding to a protein or a protein-containing complex to assist the protein folding process.
  • GO:0051082 Binding to an unfolded protein.
  • GO:0071977 Bacterial-type flagellum-dependent cell motility that results in the smooth movement of a cell through a liquid medium.
  • GO:0051701 An interaction between two organisms living together in more or less intimate association. The term host is used for the larger (macro) of the two members of a symbiosis; the various forms of symbiosis include parasitism, commensalism and mutualism.
  • GO:0042026 The process carried out by a cell that restores the biological activity of an unfolded or misfolded protein, using helper proteins such as chaperones.
  • 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:0043107 Any process involved in the controlled movement of a bacterial cell which is dependent on the presence of type IV pili. Includes social gliding motility and twitching motility.
  • GO:0006457 The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure.
