    6464   Cellular Protein Modification Process  The Covalent Alteration of One or More Amino Acids Occurring in Proteins Peptides and Nascent Polypeptides (co Translational Post Translational Modifications) Occurring At the Level of an Individual Cell. Includes the Modification of Charged Trnas That Are Destined to Occur in a Protein (pre Translation Modification). 
    8652   Cellular Amino Acid Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Amino Acids Organic Acids Containing One or More Amino Substituents. 
    9085   Lysine Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Lysine 2 6 Diaminohexanoic Acid. 
    19878   Lysine Biosynthetic Process Via Aminoadipic Acid  The Chemical Reactions and Pathways Resulting in the Formation of Lysine by the Aminoadipic Pathway. 
    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. 
    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. 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    16874   Ligase Activity  Catalysis of the Joining of Two Substances or Two Groups Within a Single Molecule with the Concomitant Hydrolysis of the Diphosphate Bond in ATP or a Similar Triphosphate. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
