    GO ID   Ontology GO Term Definition
    6206   Pyrimidine Nucleobase Metabolic Process  The Chemical Reactions and Pathways Involving Pyrimidine Nucleobases 1 3 Diazine Organic Nitrogenous Bases. 
    6213   Pyrimidine Nucleoside Metabolic Process  The Chemical Reactions and Pathways Involving Any Pyrimidine Nucleoside One of a Family of Organic Molecules Consisting of a Pyrimidine Base Covalently Bonded to Ribose (a Ribonucleoside) or Deoxyribose (a Deoxyribonucleoside). 
    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. 
    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. 
    46104   Thymidine Metabolic Process  The Chemical Reactions and Pathways Involving Thymidine Deoxyribosylthymine Thymine 2 Deoxyriboside a Deoxynucleoside Very Widely Distributed But Occurring Almost Entirely As Phosphoric Esters in Deoxynucleotides and Deoxyribonucleic Acid Dna. 
    16020   Membrane  A Lipid Bilayer Along with All the Proteins and Protein Complexes Embedded in It an Attached to It. 
    4645   Phosphorylase Activity  Catalysis of the Reaction: 1 4 Alpha D Glucosyl(n) + Phosphate = 1 4 Alpha D Glucosyl(n 1) + Alpha D Glucose 1 Phosphate. the Name Should Be Qualified in Each Instance by Adding the Name of the Natural Substrate E.g. Maltodextrin Phosphorylase Starch Phosphorylase Glycogen Phosphorylase. 
    9032   Thymidine Phosphorylase Activity  Catalysis of the Reaction: Thymidine + Phosphate = Thymine + 2 Deoxy D Ribose 1 Phosphate. 
    16154   Pyrimidine Nucleoside Phosphorylase Activity  Catalysis of the Reaction: Pyrimidine Nucleoside + Phosphate = Pyrimidine + Alpha D Ribose 1 Phosphate. 
    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. 
    16757   Transferase Activity Transferring Glycosyl Groups  Catalysis of the Transfer of a Glycosyl Group From One Compound (donor) to Another (acceptor). 
    16763   Transferase Activity Transferring Pentosyl Groups  Catalysis of the Transfer of a Pentosyl Group From One Compound (donor) to Another (acceptor).
