Protoporphyrin IX Biosynthesis
Protoporphyrin IX is an important precursor to heme, cytochrome c and chlorophylls. As a result, many organisms are able to synthesize this tetrapyrrole from basic precursors, such as glycine and succinyl-CoA , and from glutamate . Despite the large phylogenetic variation of organisms capable of synthesizing protoporphyrin IX, this process remained virtually unchanged from bacteria to mammals, with several special exceptions in higher plants.

Gem biosynthesis b
In heme biosynthesis, the enzyme ferrochelatase converts it into heme b (other names: Fe-protoporphyrin IX or protox IX).
Chlorophyll biosynthesis
In chlorophyll biosynthesis, the enzyme Mg-protoporphyrin chelatase transforms it into Mg-protoporphyrin IX .
