An adaptor for feedback regulation of heme biosynthesis by a mitochondrial protease.

Heme biosynthesis is tightly coordinated to support essential functions without accumulating toxic porphyrins and depleting cellular iron.

Heme biosynthesis is tightly coordinated to support essential functions without accumulating toxic porphyrins and depleting cellular iron. Heme induces degradation of the heme biosynthetic enzyme, 5-aminolevulinate synthase (ALAS), by the mitochondrial caseinolytic protease…
