Abstract
This invention relates to an isolated nucleic acid fragment encoding a methionine metabolic enzyme. The invention also relates to the construction of a chimeric gene encoding all or a portion of the methionine metabolic enzyme, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the methionine metabolic enzyme in a transformed host cell.
Claims12
An isolated polynucleotide selected from the group consisting of:
- (a) an isolated polynucleotide that encodes a methionyl-tRNA fomyltransferase polypeptide having a sequence identity of at least 95% when compared to a member selected from the group consisting of SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, SEQ ID NO:8, and
- (b) an isolated polynucleotide that encodes a methionyl-tRNA synthetase having a sequence identity of at least 95% when compared to a member selected from the group consisting of SEQ ID NO:10, and SEQ ID NO:12.
