Two apparent isoforms of the virulence-associated 69,000-molecular-weight protein pertactin were purified from Bordetella pertussis. Mass spectrometry showed a difference of 2,060 Da, which may result from differential C-terminal cleavage of a larger precursor. Both forms were protective in a mouse model, eliciting bactericidal antibodies and reducing respiratory tract colonization.
从百日咳博德特氏菌中纯化出了两种明显的毒力相关的69,000分子量百日咳杆菌粘附素异构体。质谱分析显示两者相差2,060道尔顿,这可能是由于较大前体的C端差异切割所致。两种形式在小鼠模型中均具有保护作用,可诱导产生杀菌抗体并减少呼吸道定植。
