淋病奈瑟菌是一种专性人类病原体,也是性传播疾病淋病的病原体。由于抗药性菌株感染的比例不断增加,这种疾病的控制受到损害,这种菌株正在以惊人的速度增长。MtrCDE三联多药外排泵属于疏水性和两亲性外排耐药-增殖-细胞分裂(HAE-RND)家族,跨N.淋病并赋予对多种抗生素和有毒化合物的抗性。我们在这里报告的晶体结构的内膜MtrD多药外排泵,这揭示了一个新的结构特征,是没有发现在其他RND外排泵。
Neisseria gonorrhoeae is an obligate human pathogen and the causative agent of the sexually-transmitted disease gonorrhea. The control of this disease has been compromised by the increasing proportion of infections due to antibiotic-resistant strains, which are growing at an alarming rate. The MtrCDE tripartite multidrug efflux pump, belonging to the hydrophobic and amphiphilic efflux resistance-nodulation-cell division (HAE-RND) family, spans both the inner and outer membranes of N. gonorrhoeae and confers resistance to a variety of antibiotics and toxic compounds. We here report the crystal structure of the inner membrane MtrD multidrug efflux pump, which reveals a novel structural feature that is not found in other RND efflux pumps.
