    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. 
    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. 
    3723   RNA Binding  Interacting Selectively and Non Covalently with an RNA Molecule or a Portion Thereof. 
    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.
