THE X-RAY STRUCTURE OF CHLOROBIUM VIBRIOFORME 5-AMINOLAEVULINIC ACID DEHYDRATASE COMPLEXED WITH A DIACID INHIBITOR
Overview
The structure of Chlorobium vibrioforme 5-aminolaevulinic acid dehydratase, (ALAD) complexed with the irreversible inhibitor 4,7-dioxosebacic acid has, been solved. The inhibitor binds by forming Schiff-base linkages with, lysines 200 and 253 at the active site. The structure reported here, provides a definition of the interactions made by both of the substrate, molecules (A-side and P-side substrates) with the C. vibrioforme ALAD and, is compared and contrasted with structures of the same inhibitor bound to, Escherichia coli and yeast ALAD. The structure suggests why, 4,7-dioxosebacic acid is a better inhibitor of the zinc-dependent ALADs, than of the zinc-independent ALADs.
