Analysis of amino acid sequences reported for the major outer membrane proteins of Escherichia coli, including the porins (OmpF, OmpC, and PhoE), the phage lambda receptor (LamB), and another protein (OmpA), revealed several regions of local homology that is statistically significant. The implications of this observation are discussed in relation to the evolutionary origins of these proteins, as well as to the mechanism of export of these proteins to the outer membrane.
对已报道的大肠杆菌主要外膜蛋白的氨基酸序列分析,包括孔蛋白(OmpF、OmpC和PhoE)、噬菌体λ受体(LamB)以及另一种蛋白(OmpA),揭示了几个具有统计学意义的局部同源区域。结合这些蛋白质的进化起源以及这些蛋白质向外膜转运的机制,对这一观察结果的意义进行了讨论。
