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.
The Pathways by Which Allantoin Is Processed and Converted to Ureidoglycolate and Then Into Metabolically Useful Substrates. E. Coli Are Able to Utilize Allantoin As a Sole Nitrogen Source Under Anaerobic Conditions by Converting It to Ureidoglycolate; This May Be Further Metabolized to Produce Glyoxylate and Thence 3 Phosphoglycerate or Alternatively Oxidized to Oxolureate Which Can Converted Into Oxamate and Carbamoylphosphate. This May Then Be Further Metabolized to Co2 Nh4+ and Atp.
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.
