    Chain A
    GO ID   Ontology GO Term Definition
    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. 
    9055   Electron Carrier Activity  Any Molecular Entity That Serves As an Electron Acceptor and Electron Donor in an Electron Transport Chain. an Electron Transport Chain Is a Process in Which a Series of Electron Carriers Operate Together to Transfer Electrons From Donors to Any of Several Different Terminal Electron Acceptors to Generate a Transmembrane Electrochemical Gradient. 
    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. 
    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. 
    51537   2 Iron 2 Sulfur Cluster Binding  Interacting Selectively and Non Covalently with a 2 Iron 2 Sulfur (2fe 2s) Cluster; This Cluster Consists of Two Iron Atoms with Two Inorganic Sulfur Atoms Found Between the Irons and Acting As Bridging Ligands.

    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. 
    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. 
    8762   Udp N Acetylmuramate Dehydrogenase Activity  Catalysis of the Reaction: Udp N Acetylmuramate + Nadp+ = Udp N Acetyl 3 O (1 Carboxyvinyl) D Glucosamine + Nadph + H+. 
    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. 
    16614   Oxidoreductase Activity Acting On Ch Oh Group of Donors  Catalysis of an Oxidation Reduction (redox) Reaction in Which a Ch Oh Group Act As a Hydrogen or Electron Donor and Reduces a Hydrogen or Electron Acceptor. 
    50660   Flavin Adenine Dinucleotide Binding  Interacting Selectively and Non Covalently with FAD Flavin Adenine Dinucleotide the Coenzyme or the Prosthetic Group of Various Flavoprotein Oxidoreductase Enzymes in Either the Oxidized Form FAD or the Reduced Form Fadh2.
