What it does, reaction by reaction

1 reactions

Heme Biosynthesis (Porphyrin Pathway) Amino Acid & Nitrogen Metabolism · Mitochondrion + cytosol

step 6 Irreversible/directional

Coproporphyrinogen III + O₂ → protoporphyrinogen IX + 2 CO₂

Converts Coproporphyrinogen III O2 into Protoporphyrinogen IX CO2

Notes

Mitochondrial intermembrane-space-facing coproporphyrinogen oxidase (CPOX) oxidatively decarboxylates two propionate side chains to vinyl groups. Molecular oxygen is required, and the product re-enters the mitochondrial compartment for final steps.
