    6730   One Carbon Metabolic Process  The Chemical Reactions and Pathways Involving the Transfer of One Carbon Units in Various Oxidation States. 
    31427   Response to Methotrexate  Any Process That Results in a Change in State or Activity of a Cell or an Organism (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of a Methotrexate Stimulus. Methotrexate Is 4 Amino 10 Methylformic Acid a Folic Acid Analogue That Is a Potent Competitive Inhibitor of Dihydrofolate Reductase. 
    46677   Response to Antibiotic  Any Process That Results in a Change in State or Activity of a Cell or an Organism (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of an Antibiotic Stimulus. an Antibiotic Is a Chemical Substance Produced by a Microorganism Which Has the Capacity to Inhibit the Growth of or to Kill Other Microorganisms. 
    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. 
    5515   Protein Binding  Interacting Selectively and Non Covalently with Any Protein or Protein Complex (a Complex of Two or More Proteins That May Include Other Nonprotein Molecules). 
    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.
