Abstract
Recombinant nucleic acids which encode aminoacyl-tRNA sythetases of enterococcal origin or portions of such enzymes, have been isolated. These nucleic acids can be used to make expression constructs and transformed host cells for the production of enterococcal aminoacyl-tRNA synthetases. They can also be used in the further isolation of nucleic acids related by DNA sequence similarities, which also encode enterococcal aminoacyl-tRNA synthetases, or portions thereof. A further embodiment of the invention is antisense nucleic acid which can hybridize to the nucleic acid which encodes the aminoacyl-tRNA synthetase of enterococci. The invention also relates to tRNA synthetases such as isolated and/or recombinant enterococcal aminoacyl-tRNA synthetases. Antibodies which bind to these enzymes can be made and can be used in the purification and study of the enzymes. Tester strains, which are cells engineered to rely on the function of the tRNA synthetase encoded by an introduced cloned gene, can be used to test the effectiveness of drug candidates in the inhibition of the essential tRNA synthetase enzyme encoded by an introduced cloned gene.
