    GO ID   Ontology GO Term Definition
    9165   Nucleotide Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Nucleotides Any Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Glycose Moiety; May Be Mono Di or Triphosphate; This Definition Includes Cyclic Nucleotides (nucleoside Cyclic Phosphates). 
    16310   Phosphorylation  The Process of Introducing a Phosphate Group Into a Molecule Usually with the Formation of a Phosphoric Ester a Phosphoric Anhydride or a Phosphoric Amide. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    166   Nucleotide Binding  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. 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    16301   Kinase Activity  Catalysis of the Transfer of a Phosphate Group Usually From ATP to a Substrate Molecule. 
    16740   Transferase Activity  Catalysis of the Transfer of a Group E.g. a Methyl Group Glycosyl Group Acyl Group Phosphorus Containing or Other Groups From One Compound (generally Regarded As the Donor) to Another Compound (generally Regarded As the Acceptor). Transferase Is the Systematic Name For Any Enzyme of EC Class 2. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
