Intimins和invasins是革兰氏阴性菌产生的毒力因子。它们含有参与与宿主细胞粘附的C-末端细胞外过客结构域和嵌入外膜中的N-末端β结构域。在这里,我们确定的域边界的E。coliintimin β-domain的结构,并利用这些信息求解其结构和一个Y.假结核侵袭两种β-结构域结构均结晶为单体,并显示先前分配给β-结构域的残基范围还包括作为乘客的一部分的蛋白酶抗性结构域。此外,我们根据高度保守的内膜蛋白和侵袭素β结构域的边界,鉴定了146个非冗余的内膜蛋白/侵袭素家族的代表性成员。然后,我们使用这组序列沿着与我们的结构数据,以找到和映射的进化限制的残基内的β结构域。
Intimins and invasins are virulence factors produced by pathogenic Gram-negative bacteria. They contain C-terminal extracellular passenger domains that are involved in adhesion to host cells and N-terminal β-domains that are embedded in the outer membrane. Here, we identify the domain boundaries of an E. coli intimin β-domain and use this information to solve its structure and the β-domain structure of a Y. pseudotuberculosis invasin. Both β-domain structures crystallized as monomers and reveal that the previous range of residues assigned to the β-domain also includes a protease resistant domain that is part of the passenger. Additionally, we identify 146 non-redundant representative members of the intimin/invasin family based on the boundaries of the highly conserved intimin and invasin β-domains. We then use this set of sequences along with our structural data to find and map the evolutionarily constrained residues within the β-domain.
