    GO ID   Ontology GO Term Definition
    8152   Metabolic Process  The Chemical Reactions and Pathways Including Anabolism and Catabolism by Which Living Organisms Transform Chemical Substances. Metabolic Processes Typically Transform Small Molecules But Also Include Macromolecular Processes Such As DNA Repair and Replication and Protein Synthesis and Degradation. 
    8615   Pyridoxine Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Pyridoxine 2 Methyl 3 Hydroxy 4 5 Bis(hydroxymethyl)pyridine One of the Vitamin B6 Compounds. 
    9228   Thiamine Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Thiamine (vitamin B1) a Water Soluble Vitamin Present in Fresh Vegetables and Meats Especially Liver. 
    42823   Pyridoxal Phosphate Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Pyridoxal Phosphate Pyridoxal Phosphorylated At the Hydroxymethyl Group of C 5 the Active Form of Vitamin B6. 
    1903600   Glutaminase Complex  A Protein Complex Which Is Capable of Glutaminase Activity. 
    3824   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. 
    4359   Glutaminase Activity  Catalysis of the Reaction: L Glutamine + H2o = L Glutamate + Nh3. 
    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). 
    16829   Lyase Activity  Catalysis of the Cleavage of C C C O C N and Other Bonds by Other Means Than by Hydrolysis or Oxidation or Conversely Adding a Group to a Double Bond. They Differ From Other Enzymes in That Two Substrates Are Involved in One Reaction Direction But Only One in the Other Direction. When Acting On the Single Substrate a Molecule Is Eliminated and This Generates Either a New Double Bond or a New Ring. 
    36381   Pyridoxal 5' Phosphate Synthase (glutamine Hydrolysing) Activity  Catalysis of the Reaction: D Ribose 5 Phosphate + D Glyceraldehyde 3 Phosphate + L Glutamine = Pyridoxal 5' Phosphate + L Glutamate + 3 H2o + Phosphate. the Reaction Occurs in Two Steps: L Glutamine + H2o = L Glutamate + Nh3 and Subsequently D Ribose 5 Phosphate + D Glyceraldehyde 3 Phosphate + Nh3 = Pyridoxal 5' Phosphate + 4 H2o + Phosphate.
