Heme synthesis and red blood cell dynamics in normal humans and in subjects with polycythemia vera, sickle-cell anemia, and pernicious anemia.
TL;DR: By following the isotope concentration in hemin isolated from the red blood cells the length of time that labeled hemoglobin remains in the blood, and thus the survival time of thered blood cells containing the labeled heme, can be determined.

δ-Aminolevulinic Acid Dehydratase of Rhodopseudomonas spheroides I. ISOLATION AND PROPERTIES
TL;DR: δ-Aminolevulinic acid dehydratase from Rhodopseudomonas spheroides, an enzyme which catalyzes the synthesis of the pyrrole, porphobilinogen, from 2 molecules of δ-aminolevulusic acid, has been purified 300- to 400-fold and exhibits many of the characteristics of an allosteric enzyme.
