    9448   Gamma Aminobutyric Acid Metabolic Process  The Chemical Reactions and Pathways Involving Gamma Aminobutyric Acid (gaba 4 Aminobutyrate) an Amino Acid Which Acts As a Neurotransmitter in Some Organisms. 
    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. 
    3867   4 Aminobutyrate Transaminase Activity  Catalysis of the Reaction: 4 Aminobutanoate + Amino Group Acceptor = Succinate Semialdehyde + Amino Acid. 
    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.
