YEAST 5-AMINOLAEVULINIC ACID DEHYDRATASE 5-HYDROXYLAEVULINIC ACID COMPLEX

OverviewOverview

The X-ray structure of the enzyme 5-aminolaevulinic acid dehydratase, (ALAD) from yeast complexed with the competitive inhibitor, 5-hydroxylaevulinic acid has been determined at a resolution of 1.9 A. The, structure shows that the inhibitor is bound by a Schiff-base link to one, of the invariant active-site lysine residues (Lys263). The inhibitor, appears to bind in two well defined conformations and the interactions, made by it suggest that it is a very close analogue of the substrate, 5-aminolaevulinic acid (ALA).
