Susceptibility of Mycobacterium tuberculosis Cytochrome bd Oxidase Mutants to Compounds Targeting the Terminal Respiratory Oxidase, Cytochrome c. Academic Article

abstract

• We deleted subunits I (cydA) and II (cydB) of the Mycobacterium tuberculosis cytochrome bd menaquinol oxidase. The resulting cydA and cydAB mutants were hypersusceptible to compounds targeting the mycobacterial bc1 menaquinol-cytochrome c oxidoreductase and exhibited bioenergetic profiles indistinguishable from strains deficient in the ABC-type transporter, CydDC, predicted to be essential for cytochrome bd assembly. These results confirm CydAB and CydDC as potential targets for drugs aimed at inhibiting a terminal respiratory oxidase implicated in pathogenesis.
