An Enzyme-Bound Bisubstrate Hybrid Inhibitor of Adenylosuccinate Synthetase.
S.Hanessian, P.P.Lu, J.Y.Sancéau, P.Chemla, K.Gohda, R.Fonne-Pfister, L.Prade, S.W.Cowan-Jacob.
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.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
