Abstract
In order to investigate the genetic basis for the observed polymorphism amongst meningococcal transferrin-binding proteins, Tbp2, the corresponding genes of different Neisseria meningitidis strains were cloned and sequenced. Comparison of the deduced amino acid (aa) sequences indicated that the Tbp2 were 76.6 to 81.2% homologous. Several stretches of aa have been found repeated both in the N- and C-terminal halves of the molecule.
摘要
为了研究脑膜炎球菌转铁蛋白结合蛋白Tbp2中观察到的多态性的遗传基础，对不同脑膜炎奈瑟菌菌株的相应基因进行了克隆和测序。推导的氨基酸（aa）序列比较表明，Tbp2的同源性为76.6%至81.2%。在分子的N端和C端两半中均发现有几段氨基酸重复。
