氟喹诺酮类药物是临床抗菌药物库中非常重要的药物;它们的成功主要是由于它们的作用模式:稳定回旋酶-DNA中间体(切割复合物),其触发导致细胞死亡的事件链。Microcin B17(MccB 17)是一种修饰的肽细菌毒素,其通过类似的作用模式起作用,但不幸的是不适合作为治疗药物。然而,它的结构和机制可以激发新的抗菌化合物的设计,这些化合物需要避免细菌对当前抗生素的耐药性上升。在这里,我们描述的调查负责MccB 17活性的结构特征和鉴定的毒素片段,保留稳定的切割复合物的能力。
Fluoroquinolones are very important drugs in the clinical antibacterial arsenal; their success is principally due to their mode of action: the stabilisation of a gyrase-DNA intermediate (the cleavage complex), which triggers a chain of events leading to cell death. Microcin B17 (MccB17) is a modified peptide bacterial toxin that acts by a similar mode of action, but is unfortunately unsuitable as a therapeutic drug. However, its structure and mechanism could inspire the design of new antibacterial compounds that are needed to circumvent the rise in bacterial resistance to current antibiotics. Here we describe the investigation of the structural features responsible for MccB17 activity and the identification of fragments of the toxin that retain the ability to stabilise the cleavage complex.
