  • GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
  • 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:0004176 Catalysis of the hydrolysis of peptide bonds, driven by ATP hydrolysis.
  • GO:0043565 Binding to DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding.
  • GO:0004252 Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine).
  • GO:0071978 Bacterial-type flagellum-dependent cell motility in which the action of numerous flagella results in the smooth movement of a group of cells along a solid surface. Swarming motility is observed in groups of bacteria.
  • GO:0071977 Bacterial-type flagellum-dependent cell motility that results in the smooth movement of a cell through a liquid medium.
  • GO:0071236 Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an antibiotic stimulus. An antibiotic is a chemical substance produced by a microorganism which has the capacity to inhibit the growth of or to kill other microorganisms.
  • GO:0034605 Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a heat stimulus, a temperature stimulus above the optimal temperature for that organism.
  • GO:0006515 The chemical reactions and pathways resulting in the breakdown of misfolded or attenuated proteins.
  • 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:0044010 A process in which planktonically growing microorganisms of the same species grow at a liquid-air interface or on a solid substrate under the flow of a liquid and produce extracellular polymers that facilitate matrix formation, resulting in a change in the organisms' growth rate and gene transcription.
  • 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:0006508 The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
  • GO:0030163 The chemical reactions and pathways resulting in the breakdown of a protein by the destruction of the native, active configuration, with or without the hydrolysis of peptide bonds.
