The OmpC, OmpF, and Lc (NmpC) porin proteins of Escherichia coli K-12 have been shown to be similar to the OmpC (36K), OmpF (35K) and OmpD (34K) porin proteins of Salmnella typhimurium LT2 in terms of function, regulation of expression, and, in the case of OmpC and OmpF proteins, equivalence of the genetic loci determining their production. However, the corresponding pairs of proteins from these two species showed only limited similarity in peptide maps and no similarity in terms of migration on polyacrylamide gels.
大肠杆菌K-12的OmpC、OmpF和Lc(NmpC)孔蛋白已被证明在功能、表达调控方面,以及就决定其产生的基因座而言(对于OmpC和OmpF蛋白),与鼠伤寒沙门氏菌LT2的OmpC(36K)、OmpF(35K)和OmpD(34K)孔蛋白相似。然而,这两个物种的相应蛋白对在肽图上仅显示出有限的相似性,在聚丙烯酰胺凝胶上的迁移方面则没有相似性。
