Asymmetric/Biological Unit(hide GO term definitions)

Chain A (CHEY_SALTY | P0A2D5)

molecular function
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
biological process
	GO:0097588	archaeal or bacterial-type flagellum-dependent cell motility	Cell motility due to movement of bacterial- or archaeal-type flagella.
	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: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.
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

Chain B (CHEZ_SALTY | P07800)

molecular function
	GO:0003824	catalytic activity	Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
	GO:0004721	phosphoprotein phosphatase activity	Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. Together with protein kinases, these enzymes control the state of phosphorylation of cell proteins and thereby provide an important mechanism for regulating cellular activity.
biological process
	GO:0097588	archaeal or bacterial-type flagellum-dependent cell motility	Cell motility due to movement of bacterial- or archaeal-type flagella.
	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:0006470	protein dephosphorylation	The process of removing one or more phosphoric residues from a protein.
	GO:0050920	regulation of chemotaxis	Any process that modulates the frequency, rate or extent of the directed movement of a motile cell or organism in response to a specific chemical concentration gradient.
cellular component
	GO:0009288	bacterial-type flagellum	A motor complex composed of an extracellular helical protein filament coupled to a rotary motor embedded in the cell envelope.
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
