Abstract

Haem a and cytochrome c were isotopically labelled in mitochondria from rat heart and liver after injection of δ-amino[2,3-3H2]laevulate, a specific haem precursor. [guanido-14C]Arginine or l-[4,5-3H2]leucine were used to label mitochondrial proteins. Half-lives were measured from biological decay in vivo and were similar (5.5–6.2 days) for haem a, cytochrome c and [14C]arginine-labelled proteins. Labelling of hepatic mitochondrial proteins with [3H2]leucine resulted in a prolonged apparent half-life.
