The most important response of Mtb to oxidative stress is provided by catalase and peroxiredoxins, both of which get their reducing equivalents through a network of disulfide proteins and, finally, from NAD(P)H. Multiple redundancies make choosing a good drug target difficult (Koul et al. 2011). Optimum efficacy can only be expected from inhibitors of the most upstream components of the redox cascades, i.e. the NAD(P)H-dependent reductases TrxB and Lpd (Jaeger & Flohe 2006).
