    6520   Cellular Amino Acid Metabolic Process  The Chemical Reactions and Pathways Involving Amino Acids Carboxylic Acids Containing One or More Amino Groups As Carried Out by Individual Cells. 
    6525   Arginine Metabolic Process  The Chemical Reactions and Pathways Involving Arginine 2 Amino 5 (carbamimidamido)pentanoic Acid. 
    6527   Arginine Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of Arginine 2 Amino 5 (carbamimidamido)pentanoic Acid. 
    6593   Ornithine Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of Ornithine an Amino Acid Only Rarely Found in Proteins But Which Is Important in Living Organisms As an Intermediate in the Reactions of the Urea Cycle and in Arginine Biosynthesis. 
    19544   Arginine Catabolic Process to Glutamate  The Chemical Reactions and Pathways Resulting in the Breakdown of Arginine Into Other Compounds Including Glutamate. 
    19545   Arginine Catabolic Process to Succinate  The Chemical Reactions and Pathways Resulting in the Breakdown of Arginine Into Other Compounds Including Succinate. 
    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. 
    8483   Transaminase Activity  Catalysis of the Transfer of an Amino Group to an Acceptor Usually a 2 Oxo Acid. 
    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. 
    30170   Pyridoxal Phosphate Binding  Interacting Selectively and Non Covalently with Pyridoxal 5' Phosphate 3 Hydroxy 5 (hydroxymethyl) 2 Methyl4 Pyridine Carboxaldehyde 5' Phosphate the Biologically Active Form of Vitamin B6. 
    43825   Succinylornithine Transaminase Activity  Catalysis of the Reaction: 2 Oxoglutarate + N(2) Succinyl L Ornithine = N Succinyl L Glutamate 5 Semialdehyde + L Glutamate.
