Abstract
The x-ray crystal structure of 5-aminolevulinate dehydratase (ALAD) of yeast complexed with the competitive inhibitor, 5-hydroxylevulinic acid, was detd. at a resoln. of 1.9 Å. The structure showed that the inhibitor was bound by a Schiff-base link to one of the invariant active site Lys residues (Lys-263). The inhibitor appeared to bind in 2 well-defined conformations and the interactions made by it suggested that it is a very close analog of the substrate, 5-aminolevulinic acid (ALA).
