    GO ID   Ontology GO Term Definition
    6096   Glycolytic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of a Carbohydrate Into Pyruvate with the Concomitant Production of a Small Amount of Atp. Glycolysis Begins with the Metabolism of a Carbohydrate to Generate Products That Can Enter the Pathway and Ends with the Production of Pyruvate. Pyruvate May Be Converted to Ethanol Lactate or Other Small Molecules or Fed Into the Tca Cycle. 
    6974   Cellular Response to DNA Damage Stimulus  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 Stimulus Indicating Damage to Its DNA From Environmental Insults or Errors During Metabolism. 
    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. 
    46835   Carbohydrate Phosphorylation  The Process of Introducing a Phosphate Group Into a Carbohydrate Any Organic Compound Based On the General Formula Cx(h2o)y. 
    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. 
    287   Magnesium Ion Binding  Interacting Selectively and Non Covalently with Magnesium (mg) Ions. 
    3872   6 Phosphofructokinase Activity  Catalysis of the Reaction: ATP + D Fructose 6 Phosphate = Adp + D Fructose 1 6 Bisphosphate. 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    9024   Tagatose 6 Phosphate Kinase Activity  Catalysis of the Reaction: ATP + D Tagatose 6 Phosphate = Adp + D Tagatose 1 6 Bisphosphate. 
    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. 
    16773   Phosphotransferase Activity Alcohol Group As Acceptor  Catalysis of the Transfer of a Phosphorus Containing Group From One Compound (donor) to an Alcohol Group (acceptor). 
    42802   Identical Protein Binding  Interacting Selectively and Non Covalently with an Identical Protein or Proteins. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
