Metabolite Identification
Common NameProtoporphyrin IX
DescriptionProtoporphyrins are tetrapyrroles containing 4 methyl, 2 propionic and 2 vinyl side chains. Protopophyrin is produced by oxidation of the methylene bridge of protoporphyrinogen. Protoporphyrin IX is the only naturally occurring isomer; it is an intermediate in heme biosynthesis, combining with ferrous iron to form protoheme IX, the heme prosthetic group of hemoglobin. Protoporphyrin IX is created by the enzyme protoporphyrinogen oxidase. The enzyme ferrochelatase converts it into heme. Protoporphyrin IX naturally occurs in small amounts in feces. It is accumulated and excreted excessively in the feces in protoporphyria and variegate porphyria. Protoporphyrin IX is also responsible for the brown pigment (Ooporphyrin) of birds' eggs Protoporphyrin IX is used as a branch point in the biosynthetic pathway leading to Heme (by insertion of iron) and chlorophylls (by insertion of Mg and further side-chain transformation).
