    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. 
    6355   Regulation of Transcription DNA Templated  Any Process That Modulates the Frequency Rate or Extent of Cellular DNA Templated Transcription. 
    7165   Signal Transduction  The Cellular Process in Which a Signal Is Conveyed to Trigger a Change in the Activity or State of a Cell. Signal Transduction Begins with Reception of a Signal (e.g. a Ligand Binding to a Receptor or Receptor Activation by a Stimulus Such As Light) or For Signal Transduction in the Absence of Ligand Signal Withdrawal or the Activity of a Constitutively Active Receptor. Signal Transduction Ends with Regulation of a Downstream Cellular Process E.g. Regulation of Transcription or Regulation of a Metabolic Process. Signal Transduction Covers Signaling From Receptors Located On the Surface of the Cell and Signaling Via Molecules Located Within the Cell. For Signaling Between Cells Signal Transduction Is Restricted to Events At and Within the Receiving Cell. 
    16310   Phosphorylation  The Process of Introducing a Phosphate Group Into a Molecule Usually with the Formation of a Phosphoric Ester a Phosphoric Anhydride or a Phosphoric Amide. 
    18106   Peptidyl Histidine Phosphorylation  The Phosphorylation of Peptidyl Histidine to Form Peptidyl 1' Phospho L Histidine (otherwise Known As Tau Phosphohistidine Tele Phosphohistidine) or Peptidyl 3' Phospho L Histidine (otherwise Known As Pi Phosphohistidine Pros Phosphohistidine). 
    23014   Signal Transduction by Protein Phosphorylation  A Process in Which the Transfer of One or More Phosphate Groups to a Substrate Transmits a Signal to the Phosphorylated Substrate. 
    5622   Intracellular  The Living Contents of a Cell; the Matter Contained Within (but Not Including) the Plasma Membrane Usually Taken to Exclude Large Vacuoles and Masses of Secretory or Ingested Material. in Eukaryotes It Includes the Nucleus and Cytoplasm. 
    16020   Membrane  A Lipid Bilayer Along with All the Proteins and Protein Complexes Embedded in It an Attached to It. 
    155   Phosphorelay Sensor Kinase Activity  Catalysis of the Phosphorylation of a Histidine Residue in Response to Detection of an Extracellular Signal Such As a Chemical Ligand or Change in Environment to Initiate a Change in Cell State or Activity. the Two Component Sensor Is a Histidine Kinase That Autophosphorylates a Histidine Residue in Its Active Site. the Phosphate Is Then Transferred to an Aspartate Residue in a Downstream Response Regulator to Trigger a Response. 
    166   Nucleotide Binding  Interacting Selectively and Non Covalently with a Nucleotide Any Compound Consisting of a Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Ribose or Deoxyribose. 
    4673   Protein Histidine Kinase Activity  Catalysis of the Reaction: ATP + Protein L Histidine = Adp + Protein Phospho L Histidine. 
    4871   Signal Transducer Activity  Conveys a Signal Across a Cell to Trigger a Change in Cell Function or State. a Signal Is a Physical Entity or Change in State That Is Used to Transfer Information in Order to Trigger a Response. 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    16301   Kinase Activity  Catalysis of the Transfer of a Phosphate Group Usually From ATP to a Substrate Molecule. 
    16740   Transferase Activity  Catalysis of the Transfer of a Group E.g. a Methyl Group Glycosyl Group Acyl Group Phosphorus Containing or Other Groups From One Compound (generally Regarded As the Donor) to Another Compound (generally Regarded As the Acceptor). Transferase Is the Systematic Name For Any Enzyme of EC Class 2. 
    16772   Transferase Activity Transferring Phosphorus Containing Groups  Catalysis of the Transfer of a Phosphorus Containing Group From One Compound (donor) to Another (acceptor).
