Gene Information

human ... ALAD(210)

General description

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.

Specificity

Anti-ALAD (AB2) antibody detects bovine, human, mouse, and rat porphobilinogen synthase (delta-aminolevulinate dehydratase) enzymes.

Immunogen

Synthetic peptide directed towards the middle region of human ALAD

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 (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).

Sequence

Synthetic peptide located within the following region: SVMSYSAKFASCFYGPFRDAAKSSPAFGDRRCYQLPPGARGLALRAVDRD

Physical form

Purified antibody supplied in 1x PBS buffer with 0.09% (w/v) sodium azide and 2% sucrose.

Human porphobilinogen synthase (PBGS) is a main target in lead poisoning. Human PBGS purifies with eight Zn(II) per homo-octamer; four ZnA have predominantly nonsulfur ligands, and four ZnB have predominantly sulfur ligands. Only four Zn(II) are required for activity. To
