项目摘要
We are in danger of heading for a crisis in infectious diseases. The combined effects of multi-drug-resistant bacterial infections, such as MRSA and C. difficile, and the lack of new antibiotics being produced by pharmaceutical companies, means that academic labs need to make a more significant contribution to solving this problem. We are studying an enzyme from bacteria called DNA gyrase, which is already the target for antibiotics such as Cipro (ciprofloxacin), the drug used to combat anthrax during the scare in the USA in 2001. Unfortunately, due to resistance problems, Cipro is no longer as effective as it was and the search is on for antibiotics to replace it. Microcin B17 is a toxin produced by bacteria to kill other bacteria, and it works in a manner similar to Cipro but is unlikely to be affected by the same resistance problems. We aim to understand the molecular details of how Microcin B17 works such that this information can be used in the future design of new antibiotics that can potentially replace Cipro.
我们正面临传染病危机的危险。多重耐药细菌感染,如MRSA和C。艰难梭菌,以及制药公司生产的新抗生素的缺乏,意味着学术实验室需要为解决这一问题做出更大的贡献。我们正在研究一种来自细菌的酶,称为DNA促旋酶,它已经是抗生素的目标,如环丙沙星(环丙沙星),在2001年美国恐慌期间用于对抗炭疽的药物。不幸的是,由于耐药性问题,Cipro不再像以前那样有效,人们正在寻找抗生素来取代它。Microcin B17是一种由细菌产生的毒素,可以杀死其他细菌,它的作用方式类似于Cipro,但不太可能受到相同的耐药性问题的影响。我们的目标是了解Microcin B17如何工作的分子细节,以便这些信息可以用于未来设计可能取代Cipro的新抗生素。
