| 摘要 |
<p>The present invention provides an oligonucleotide (aarC) which encodes a novel bacterial polypeptide (aarC) that is essential for the viability of bacteria. The invention provides recombinant expression vectors comprising the nucleotide sequence encoding AarC, as well as host cells containing these expression vectors. Further provided herein are methods for screening bacteria which contain (aarC) or variants or homologs thereof. Also provided are methods for using the (aarC) oligonucleotide sequence to screen antimicrobials which target AarC activity in gram negative and gram positive bacteria. Additionally, the invention provides for the use of (aarC) in diagnostic assays which utilize the (aarC) oligonucleotide to hybridize with nucleic acid sequences encoding AarC as well as with AarC mRNA. The invention further describes monoclonal and polyclonal AarC antibodies and their use in diagnostic assays for the detection of bacteria which express AarC.</p> |
