Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 4.99.1.1

Enzymes and Genes:
porphyrinogen peroxidase Inferred from experiment : yfeX
EfeB dimer Inferred from experiment : efeB
ferrochelatase Inferred from experiment : hemH

In Pathway: heme biosynthesis I (aerobic) , superpathway of heme biosynthesis from uroporphyrinogen-III , heme biosynthesis II (anaerobic)
