The zinc-containing enzyme ALAD catalyzes the second stage of porphyrin synthesis. Substitution of Zn by Pb causes the pathway to shut down, leading to anemia and neurological damage from excess 5-aminolevulinic acid. We discuss computational models of several competing mechanisms for the activity of the native form of ALAD, and the effect of lead substitution upon them.
