    GO ID   Ontology GO Term Definition
    6164   Purine Nucleotide Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of a Purine Nucleotide a Compound Consisting of Nucleoside (a Purine Base Linked to a Deoxyribose or Ribose Sugar) Esterified with a Phosphate Group At Either the 3' or 5' Hydroxyl Group of the Sugar. 
    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. 
    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. 
    16853   Isomerase Activity  Catalysis of the Geometric or Structural Changes Within One Molecule. Isomerase Is the Systematic Name For Any Enzyme of EC Class 5. 
    34023   5 (carboxyamino)imidazole Ribonucleotide Mutase Activity  Catalysis of the Reaction: 5 Carboxyamino 1 (5 Phospho D Ribosyl)imidazole = 5 Amino 1 (5 Phospho D Ribosyl)imidazole 4 Carboxylate.
