    GO ID   Ontology GO Term Definition
    6779   Porphyrin Containing Compound Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Any Member of a Large Group of Derivatives or Analogs of Porphyrin. Porphyrin Consists of a Ring of Four Pyrrole Nuclei Linked Each to the Next At Their Alpha Positions Through a Methine Group. 
    6782   Protoporphyrinogen Ix Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Protoporphyrinogen Ix. 
    15995   Chlorophyll Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Chlorophyll Any Compound of Magnesium Complexed in a Porphyrin (tetrapyrrole) Ring and Which Functions As a Photosynthetic Pigment From Less Complex Precursors. 
    33014   Tetrapyrrole Biosynthetic Process  The Chemical Reactions and Pathways Leading to the Formation of Tetrapyrroles Natural Pigments Containing Four Pyrrole Rings Joined by One Carbon Units Linking Position 2 of One Pyrrole Ring to Position 5 of the Next. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    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. 
    16853   Isomerase Activity  Catalysis of the Geometric or Structural Changes Within One Molecule. Isomerase Is the Systematic Name For Any Enzyme of EC Class 5. 
    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.
