The cell-surface proteins of the infective bacteria Streptococcus and Staphylococcus are probably involved in the process of infection. These proteins share many features including secretion signal peptides, cell-wall spanning regions, membrane anchor domains and repeated domains of various functions. These common features may have evolved by gene duplication and swapping of gene fragments.
感染性细菌链球菌和葡萄球菌的细胞表面蛋白可能参与感染过程。这些蛋白具有许多共同特征,包括分泌信号肽、跨细胞壁区域、膜锚定结构域和具有各种功能的重复结构域。这些共同特征可能是通过基因复制和基因片段交换进化而来的。
