Abstract

The structural gene encoding the 70-kDa outer membrane protein FrpB of Neisseria meningitidis was cloned and sequenced. A mutant lacking FrpB was constructed. No difference in iron utilization between the mutant and the parental strain was observed. A minor effect of the mutation on serum resistance was observed. A topology model for FrpB in the outer membrane is proposed.

摘要

对脑膜炎奈瑟菌70 kDa外膜蛋白FrpB的编码结构基因进行了克隆和测序。构建了一个缺失FrpB的突变体。未观察到该突变体与亲本菌株在铁利用方面的差异。观察到该突变对血清抗性有轻微影响。提出了外膜中FrpB的拓扑模型。
