'''DESIGN, SYNTHESIS, AND X-RAY CRYSTAL STRUCTURE OF AN ENZYME BOUND BISUBSTRATE HYBRID INHIBITOR OF ADENYLOSUCCINATE SYNTHETASE'''<br />


==Overview==
==DESIGN, SYNTHESIS, AND X-RAY CRYSTAL STRUCTURE OF AN ENZYME BOUND BISUBSTRATE HYBRID INHIBITOR OF ADENYLOSUCCINATE SYNTHETASE==
Two relatively weak herbicides, hydantocidin phosphate and hadacidin were, linked by a C(3) chain to afford a potent inhibitor (the 2S hybrid is, shown) of the enzyme adenylosuccinate synthetase. The crystal structures, of the bisubstrate-enzyme complexes were determined.

Two relatively weak herbicides, hydantocidin phosphate and hadacidin were linked by a C(3) chain to afford a potent inhibitor (the 2S hybrid is shown) of the enzyme adenylosuccinate synthetase. The crystal structures of the bisubstrate-enzyme complexes were determined.
