ALAD, Human

(Aminolevulinate delta-dehydratase, ALADH, PBGS, Porphobilinogen synthase, delta-aminolevulinic acid dehydratase, EC 4.2.1.24.)

ALAD form porphobilinogen (a precursor of heme, cytochromes and other hemoproteins) by catalyzing the compression of 2 molecules of delta-aminolevulinate. ALAD catalyzes the second step in the porphyrin and heme biosynthetic pathway; zinc is vital for enzymatic activity. ALAD has 8 identical subunits and its enzymatic activity is inhibited by lead. Mutations in the ALAD structural gene are the source for high sensitivity to lead poisoning and acute hepatic porphyria.

ALAD Human Recombinant produced in E. coli is a single polypeptide chain containing 354 amino acids (1-330) and having a molecular mass of 38.8kDa. ALAD is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Purity: Greater than 85% as determined by SDS-PAGE.

Source: E.coli.

Physical Appearance: Sterile Filtered colorless solution.

Formulation: The ALAD solution (1mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 100mM NaCl and 10% glycerol.
