Transfer of a point mutation in Mycobacterium tuberculosis inhA resolves the target of isoniazid

Article Abstract:

The precise mechanism of action of Isoniazid, the most effective antituberculosis drug, is yet to be configured. A study conducted by using specialized linkage transduction to transfer a single point mutation allele (S94A) within the putative target gene inhA in Mycobacterium tuberculosis found that the inhA(S94A) was sufficient to confer clinically relevant levels of resistance to isonizad killing and inhibition of mycolic acid biosynthesis and establishes InhA as the primary target of isoniazid action in M. tuberculosis.
