摘要: The present invention provides novel nucleic acid molecules coding for sigma subunits of Mycobacterium tuberculosis RNA polymerase. It also relates to polypeptides, referred to as SigA and SigB, encoded by such nucleic acid molecules, as well as to vectors and host cells transformed with the said nucleic acid molecules. The invention further provides screening assays for compounds which inhibit the interaction between a sigma subunit and a core RNA polymerase.

摘要: The present invention relates to recombinant vectors which are useful for direct selection of colonies harboring recombinant plasmids, on basis of the loss of expression of a gene coding for an AsiA polypeptide from E. coli bacteriophage T4, the expression of which would normally have resulted in toxicity to the bacterial host. The invention also relates to host cells harboring the vectors, as well as to methods utilizing the vectors, for the selection of nucleic acid clones.
