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 Chemical Reactions and Pathways Resulting in the Formation of Siderophores Low Molecular Weight Fe(iii) Chelating Substances Made by Aerobic or Facultatively Anaerobic Bacteria Especially When Growing Under Iron Deficient Conditions. the Complexes of Fe(3+) Siderophores Have Very High Stability Constants and Are Taken Up by Specific Transport Systems by Microorganisms; the Subsequent Release of Iron Requires Enzymatic Action.
Interacting Selectively and Non Covalently with a Nucleotide Any Compound Consisting of a Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Ribose or Deoxyribose.
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.
