摘要：value of 0.87 μg/mL. The interaction between the compound and protein was analysed by surface plasmon resonance and circular dichroism. Based on the in silico molecular docking results, the essential amino acids in the binding pocket were then confirmed by site-directed mutagenesis. Overexpression of DHQS reduced the antibacterial activity of IMB-T130 in cells, verifying that DHQS is the target of IMB-T130. IMB-T130 inhibited standard and drug-resistant M. tuberculosis strains by targeting DHQS. Our findings improve our understanding of MtDHQS and make it to be a potential target for new anti-TB drug discovery.
