The amino acid sequences of the Bacillus subtilis flagellar proteins, FliP, FliQ, FliR and FlhB, as deduced from their respective nucleotide sequences, were found to share significant homology to the Shigella flexneri Spa24, Spa9, Spa29 and Spa40 virulence proteins, respectively. These proteins are required for the presentation of surface plasmid antigens. These results further support the growing hypothesis that a superfamily of proteins exists for the biosynthesis of supramolecular structures that lie in an external to the cell membrane.
从各自核苷酸序列推导出来的枯草芽孢杆菌鞭毛蛋白FliP、FliQ、FliR和FlhB的氨基酸序列，分别被发现与福氏志贺氏菌的Spa24、Spa9、Spa29和Spa40毒力蛋白有显著同源性。这些蛋白质是表面质粒抗原呈递所必需的。这些结果进一步支持了一种越来越流行的假说，即存在一个蛋白质超家族，用于生物合成位于细胞膜外部的超分子结构。
