    6744   Ubiquinone Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Ubiquinone a Lipid Soluble Electron Transporting Coenzyme. 
    8299   Isoprenoid Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Any Isoprenoid Compound Isoprene (2 Methylbuta 1 3 Diene) or Compounds Containing or Derived From Linked Isoprene (3 Methyl 2 Butenylene) Residues. 
    16114   Terpenoid Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Terpenoids Any Member of a Class of Compounds Characterized by an Isoprenoid Chemical Structure. 
    19288   Isopentenyl Diphosphate Biosynthetic Process Methylerythritol 4 Phosphate Pathway  The Chemical Reactions and Pathways Resulting in the Formation of Isopentenyl Diphosphate by the Mevalonate Independent Pathway. Isopentenyl Diphosphate (ipp) Is the Fundamental Unit in Isoprenoid Biosynthesis and Is Biosynthesized From Pyruvate and Glyceraldehyde 3 Phosphate Via Intermediates Including 1 Deoxy D Xylulose 5 Phosphate. 
    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. 
    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. 
    42380   Hydroxymethylbutenyl Pyrophosphate Reductase Activity  Catalysis of the Formation of Both Isopentenyl Pyrophosphate and Dimethylallyl Pyrophosphate From (e) 4 Hydroxy 3 Methyl But 2 Enyl Pyrophosphate. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion. 
    51536   Iron Sulfur Cluster Binding  Interacting Selectively and Non Covalently with an Iron Sulfur Cluster a Combination of Iron and Sulfur Atoms. 
    51538   3 Iron 4 Sulfur Cluster Binding  Interacting Selectively and Non Covalently with a 3 Iron 4 Sulfur (3fe 4s) Cluster; This Cluster Consists of Three Iron Atoms with the Inorganic Sulfur Atoms Found Between the Irons and Acting As Bridging Ligands. It Is Essentially a 4fe 4s Cluster with One Iron Missing. 
    51745   4 Hydroxy 3 Methylbut 2 En 1 Yl Diphosphate Reductase Activity  Catalysis of the Reaction: (e) 4 Hydroxy 3 Methylbut 2 En 1 Yl Diphosphate + Nad(p)h + H+ = Isopentenyl Diphosphate + Nad(p)+ + H2o.
