They found that deficiencies in an enzyme called catalase-peroxidase, encoded by a gene called katG, make drug-resistant TB more susceptible to bedaquiline. Mutations in katG are the most common ...

Liu and his team of researchers hope that by gaining a thorough understanding of how the enzyme works, they can find strategies to reduce the catalase function while boosting the peroxidase activity ...

Schematic illustration of NB-rGO Reactions in Bioassays. Researchers were able to synthesize a peroxidase-mimicking nanozyme with superior catalytic activity and selectivity toward hydrogen peroxide.
