The terminal three steps in haem biosynthesis are the oxidative decarboxylation of coproporphyrinogen III to protoporphyrinogen IX, followed by the six-electron oxidation of protoporphyrinogen to protoporphyrin IX, and finally the insertion of ferrous iron to form haem. Interestingly, Nature has evolved distinct enzymic machinery to deal with the antepenultimate (coproporphyrinogen oxidase) and...
