'''ADENYLOSUCCINATE SYNTHETASE IN COMPLEX WITH THE NATURAL FEEDBACK INHIBITOR AMP'''
===ADENYLOSUCCINATE SYNTHETASE IN COMPLEX WITH THE NATURAL FEEDBACK INHIBITOR AMP===




==Overview==
<!--
(+)-Hydantocidin, a recently discovered natural spironucleoside with potent herbicidal activity, is shown to be a proherbicide that, after phosphorylation at the 5' position, inhibits adenylosuccinate synthetase, an enzyme involved in de novo purine synthesis. The mode of binding of hydantocidin 5'-monophosphate to the target enzyme was analyzed by determining the crystal structure of the enzyme-inhibitor complex at 2.6-A resolution. It was found that adenylosuccinate synthetase binds the phosphorylated compound in the same fashion as it does adenosine 5'-monophosphate, the natural feedback regulator of this enzyme. This work provides the first crystal structure of a herbicide-target complex reported to date.
The line below this paragraph, {{ABSTRACT_PUBMED_8790347}}, adds the Publication Abstract to the page
