Abstract excerpt
The first step of tryptophan biosynthesis is catalyzed by anthranilate synthase (AS), which is normally subject to feedback inhibition by tryptophan. Three independent trp5 mutants defective in the Arabidopsis thaliana AS alpha subunit structural gene ASA1 were identified by selection for resista...
