General description

The ALAD enzyme is composed of 8 identical subunits and catalyzes the condensation of 2 molecules of delta-aminolevulinate to form porphobilinogen (a precursor of heme, cytochromes and other hemoproteins). ALAD catalyzes the second step in the porphyrin and heme biosynthetic pathway; zinc is essential for enzymatic activity. ALAD enzymatic activity is inhibited by lead and a defect in the ALAD structural gene can cause increased sensitivity to lead poisoning and acute hepatic porphyria. (provided by RefSeq)

Application

Anti-ALAD antibody produced in mouse is suitable for western blot application.

Biochem/physiol Actions

The cytosolic ALAD (δ-aminolevulinic acid dehydratase) plays a vital role in the heme biosynthetic pathway. It facilitates the second step, which is a condensation reaction of 5-aminolevulinic acid and forms a monopyrrole termed as porphobilinogen. It is one of the main targets of lead toxicity. Lead replaces zinc present in ALAD, leading to inactivation of the enzyme. Deficiency in ALAD causes ALAD deficiency porphyria (ADP).

Porphobilinogen synthase (PBGS) catalyzes the first common step in tetrapyrrole (e.g. heme, chlorophyll) biosynthesis. Human PBGS exists as an equilibrium of high activity octamers, low activity hexamers, and alternate dimer configurations that dictate the stoichiometry and architecture of further assembly.
