Abstract
This invention relates to isolated nucleic acid fragments encoding phosphoribosylanthranilate isomerases, a tryptophan biosynthetic enzyme. The invention also relates to the construction of a chimeric gene comprising the nucleic acid fragment, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the phosphoribosylanthranilate isomerase in a transformed host cell.
