    GO ID   Ontology GO Term Definition
    160   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. 
    6935   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). 
    97588   Archaeal or Bacterial Type Flagellum Dependent Cell Motility  Cell Motility Due to Movement of Bacterial or Archaeal Type Flagella. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5515   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). 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
