Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (CHEY_ECOLI | P0AE67)
molecular function
    GO:0016407    acetyltransferase activity    Catalysis of the transfer of an acetyl group to an acceptor molecule.
    GO:0000287    magnesium ion binding    Interacting selectively and non-covalently with magnesium (Mg) ions.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
    GO:0097588    archaeal or bacterial-type flagellum-dependent cell motility    Cell motility due to movement of bacterial- or archaeal-type flagella.
    GO:0071973    bacterial-type flagellum-dependent cell motility    Cell motility due to the motion of one or more bacterial-type flagella. A bacterial-type flagellum is a motor complex composed of an extracellular helical protein filament coupled to a rotary motor embedded in the cell envelope.
    GO:0006935    chemotaxis    The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).
    GO:0018393    internal peptidyl-lysine acetylation    The addition of an acetyl group to a non-terminal lysine residue in a protein.
    GO:0000160    phosphorelay signal transduction system    A conserved series of molecular signals found in prokaryotes and eukaryotes; involves autophosphorylation of a histidine kinase and the transfer of the phosphate group to an aspartate that then acts as a phospho-donor to response regulator proteins.
    GO:0006473    protein acetylation    The addition of an acetyl group to a protein amino acid. An acetyl group is CH3CO-, derived from acetic [ethanoic] acid.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
