Abstract excerpt
Delta-aminolevulinic acid dehydratase (ALAD) is a cytosolic enzyme in the heme biosynthetic pathway. The ALAD is controlled by two codominant alleles (ALAD1 and ALAD2), which result in a Asn-Lys substitution at amino acid position 59 of the mature enzyme based on a single nucleotide polymorphism (SNP) (G177C) leading three phenotypes (ALAD1-1, ALAD1-2, and ALAD2-2). Previous studies have shown that this...
