Abstract
This invention relates to an isolated nucleic acid fragment encoding a histidine biosynthetic enzyme. The invention also relates to the construction of a chimeric gene encoding all or a portion of the histidine biosynthetic enzyme, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the histidine biosynthetic enzyme in a transformed host cell.
Claims14
An isolated polynucleotide comprising:
- (a) a nucleotide sequence encoding a polypeptide having HisHF glutamine amidotransferase activity, wherein the polypeptide has an amino acid sequence of at least 90% sequence identity, based on the Clustal method of alignment, when compared to SEQ ID NO:2, or
- (b) a full complement of the nucleotide sequence of (a).
