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.
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.
Catalysis of the Cleavage of C C C O C N and Other Bonds by Other Means Than by Hydrolysis or Oxidation or Conversely Adding a Group to a Double Bond. They Differ From Other Enzymes in That Two Substrates Are Involved in One Reaction Direction But Only One in the Other Direction. When Acting On the Single Substrate a Molecule Is Eliminated and This Generates Either a New Double Bond or a New Ring.
