The Chemical Reactions and Pathways Resulting in the Formation of a Purine Nucleotide a Compound Consisting of Nucleoside (a Purine Base Linked to a Deoxyribose or Ribose Sugar) Esterified with a Phosphate Group At Either the 3' or 5' Hydroxyl Group of the Sugar.
The Chemical Reactions and Pathways Resulting in the Formation of a Purine Ribonucleotide a Compound Consisting of Ribonucleoside (a Purine Base Linked to a Ribose Sugar) Esterified with a Phosphate Group At Either the 3' or 5' Hydroxyl Group of the Sugar.
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.
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.
