The results showed that norfloxacin was situated in the minor groove of DNA, binding to the TCGA region of d [ATATCGATAT] 2- Specific hydrogen bonds were formed between norfloxacin and guanine base of DNA during the 2 ns MD, which may be the reason for the preferentiality of quinolone antibacterial towards the guanine base of DNA duplex.展开更多
