Intramitochondrial loci for delta-aminolaevulate synthetase and ferrochelatase, the initial and final enzymes in haem synthesis, have been found in rat liver. Two different methods of fractionation were applied to mitochondria: (a) sonication and density-gradient centrifugation; (b) treatment with digitonin and differential centrifugation. Similar results were obtained with each technique. delta-Aminolaevulate synthetase is distributed similarly to two known matrix enzymes, malate dehydrogenase and glutamate dehydrogenase. Ferrochelatase is firmly bound to the the inner mitochondrial membrane. These results are considered in terms of the regulation of haem synthesis and in relation to mitochondrial biogenesis.
