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).
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.
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.
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.
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.
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.
