    GO ID   Ontology GO Term Definition
    6189   'de Novo' Imp Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Imp Inosine Monophosphate by the Stepwise Assembly of a Purine Ring On Ribose 5 Phosphate. 
    55114   Oxidation Reduction Process  A Metabolic Process That Results in the Removal or Addition of One or More Electrons to or From a Substance with or Without the Concomitant Removal or Addition of a Proton or Protons. 
    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. 
    4638   Phosphoribosylaminoimidazole Carboxylase Activity  Catalysis of the Reaction: 5 Amino 1 (5 Phospho D Ribosyl)imidazole 4 Carboxylate + 2 H(+) = 5 Amino 1 (5 Phospho D Ribosyl)imidazole + Co(2). 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion. 
    51287   NAD Binding  Interacting Selectively and Non Covalently with Nicotinamide Adenine Dinucleotide a Coenzyme Involved in Many Redox and Biosynthetic Reactions; Binding May Be to Either the Oxidized Form Nad+ or the Reduced Form Nadh.
