== Publication Abstract from PubMed ==
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.
