Rational herbicide design by inhibition of tryptophan biosynthesis
摘要:
Compounds designed to mimic the tryptophan synthase a subunit reactive intermediate were found to be potent inhibitors of the enzyme. These compounds are herbicidal and the herbicidal mode of action was demonstrated to be due to disruption of tryptophan biosynthesis. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
The invention relates to methods of identifying inhibitors of tryptophan synthase (TS) that are useful as herbicides, the TS inhibiting herbicides, methods of designing variants of the TS enzyme that are resistant to the herbicides of the invention and other known herbicides, the TS enzyme variants themselves, polynucleotides encoding these TS enzyme variants, plants expressing the TS enzyme variants, and methods of weed control.
