Protoporphyrin is an intermediate in the Heme synthesis pathway and is formed from Protoporphyrinogen III in a reaction catalyzed by the enzyme Protoporphyrin III oxidase. Iron in the ferrous state is added to Protoporphyrin to form heme in a reaction catalyzed by the enzyme ferrochelatase. Protoporphyrin has been found to activate guanylate cyclase and has been found to induce apoptosis in HeLa cells.

 

Protoporphyrin is an important precursor to biologically essential prosthetic groups such as heme, cytochrome c, and chlorophylls. As a result, a number of organisms are able to synthesize this tetrapyrrole from basic precursors such as glycine and succinyl CoA, or glutamate. Despite the wide range of organisms that synthesize protoporphyrin IX the process is largely conserved from bacteria to mammals with a few distinct exceptions in higher plants.


In the biosynthesis of those molecules, the metal cation is inserted into protoporphyrin by enzymes called chelatases. For example, ferrochelatase converts the compound into heme b (i.e. Fe-protoporphyrin or protoheme). In chlorophyll biosynthesis, the enzyme magnesium chelatase converts it into Mg-protoporphyrin.
