    Chain A
    GO ID   Ontology GO Term Definition
    6260   DNA Replication  The Cellular Metabolic Process in Which a Cell Duplicates One or More Molecules of Dna. DNA Replication Begins When Specific Sequences Known As Origins of Replication Are Recognized and Bound by Initiation Proteins and Ends When the Original DNA Molecule Has Been Completely Duplicated and the Copies Topologically Separated. the Unit of Replication Usually Corresponds to the Genome of the Cell an Organelle or a Virus. the Template For Replication Can Either Be an Existing DNA Molecule or Rna. 
    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. 
    9263   Deoxyribonucleotide Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of a Deoxyribonucleotide a Compound Consisting of Deoxyribonucleoside (a Base Linked to a Deoxyribose Sugar) Esterified with a Phosphate Group At Either the 3' or 5' Hydroxyl Group of the Sugar. 
    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. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5971   Ribonucleoside Diphosphate Reductase Complex  An Enzyme Complex Composed of 2 4 or More Subunits Which Usually Contains Nonheme Iron and Requires ATP For Catalysis. Catalyzes the Formation of 2' Deoxyribonucleoside Diphosphate From Ribonucleoside Diphosphate Using Either Thioredoxin Disulfide or Glutaredoxin Disulfide As an Acceptor. 
    166   Nucleotide Binding  Interacting Selectively and Non Covalently with a Nucleotide Any Compound Consisting of a Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Ribose or Deoxyribose. 
    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. 
    4748   Ribonucleoside Diphosphate Reductase Activity Thioredoxin Disulfide As Acceptor  Catalysis of the Reaction: 2' Deoxyribonucleoside Diphosphate + Thioredoxin Disulfide + H2o = Ribonucleoside Diphosphate + Thioredoxin. Thioredoxin Disulfide Is the Oxidized Form of Thioredoxin. 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    16491   Oxidoreductase Activity  Catalysis of an Oxidation Reduction (redox) Reaction a Reversible Chemical Reaction in Which the Oxidation State of an Atom or Atoms Within a Molecule Is Altered. One Substrate Acts As a Hydrogen or Electron Donor and Becomes Oxidized While the Other Acts As Hydrogen or Electron Acceptor and Becomes Reduced.
