Delta-Aminolevulinate dehydratase (Porphobilinogen synthase, ALA dehydratase), a zinc metalloenzyme, catalyzes the second step of porphyrin biosynthesis and the first common step in the biosynthesis of all biological tetrapyrroles including hemes, chlorophylls and vitamin B12. Hereditary insufficiency of porphobilinogen synthase causes porphobilinogen synthase (or ALA dehydratase) deficiency poprhyria. In addition to heme biosynthesis ALAD may be an important proteosome interacting protein.
Synonyms: Anti-delta-Aminolevulinate dehydratase; Anti-ALADH; Anti-MGC5057
Storage: -20C
Application: Anti-ALAD (AB2) antibody is used to tag porphobilinogen synthase (delta-Aminolevulinate dehydratase) proteins for detection and quantitation by Western blotting and in cells and tissues by immunohistochemical (IHC) techniques. It is used as a probe to study the role of this tetrapyrrole synthesizing enzyme in lead poisoning sensitivity, poprhyria and possibly some cancers.
Biochem Physiol Actions: The cytosolic ALAD (d-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).
