The Escherichia coli BarA-UvrY two-component system is needed for efficient switching between glycolytic and gluconeogenic carbon sources.
Pernestig AK, Georgellis D, Romeo T, Suzuki K, Tomenius H, Normark S, Melefors O. Pernestig AK, et al. J Bacteriol. 2003 Feb;185(3):843-53. doi: 10.1128/jb.185.3.843-853.2003. J Bacteriol. 2003. PMID: 12533459 Free PMC article.
Sensitivity of Escherichia coli to various beta-lactams is determined by the interplay of outer membrane permeability and degradation by periplasmic beta-lactamases: a quantitative predictive treatment.
Nikaido H, Normark S. Nikaido H, et al. Mol Microbiol. 1987 Jul;1(1):29-36. doi: 10.1111/j.1365-2958.1987.tb00523.x. Mol Microbiol. 1987. PMID: 3330755
Curli fibers are highly conserved between Salmonella typhimurium and Escherichia coli with respect to operon structure and regulation.
Römling U, Bian Z, Hammar M, Sierralta WD, Normark S. Römling U, et al. J Bacteriol. 1998 Feb;180(3):722-31. doi: 10.1128/JB.180.3.722-731.1998. J Bacteriol. 1998. PMID: 9457880 Free PMC article.
Cloning and characterization of the two divergently transcribed operons required for curli biogenesis, csgBA(C) and csgDEFG, from S. typhimurium SR-11 revealed the same gene order and flanking genes as in Escherichia coli. ...The high degree of conservation at the protein …

The phoP locus influences processing and presentation of Salmonella typhimurium antigens by activated macrophages.
Wick MJ, Harding CV, Twesten NJ, Normark SJ, Pfeifer JD. Wick MJ, et al. Mol Microbiol. 1995 May;16(3):465-76. doi: 10.1111/j.1365-2958.1995.tb02411.x. Mol Microbiol. 1995. PMID: 7565107
Thus, phoP-regulated gene products decrease the processing and presentation of S. typhimurium antigens, demonstrating a role for this virulence locus in the inhibition of the induction of specific immunity....

Expression of thin aggregative fimbriae promotes interaction of Salmonella typhimurium SR-11 with mouse small intestinal epithelial cells.
Sukupolvi S, Lorenz RG, Gordon JI, Bian Z, Pfeifer JD, Normark SJ, Rhen M. Sukupolvi S, et al. Infect Immun. 1997 Dec;65(12):5320-5. doi: 10.1128/IAI.65.12.5320-5325.1997. Infect Immun. 1997. PMID: 9393832 Free PMC article.
In this paper we demonstrate that elimination of production of thin aggregative fiber by a transposon insertion within the gene encoding the subunit protein of the fiber reduced binding of S. typhimurium SR-11 to a conditionally immortalized proximal small intestinal epith …

Parameters that influence the efficiency of processing antigenic epitopes expressed in Salmonella typhimurium.
Wick MJ, Harding CV, Normark SJ, Pfeifer JD. Wick MJ, et al. Infect Immun. 1994 Oct;62(10):4542-8. doi: 10.1128/IAI.62.10.4542-4548.1994. Infect Immun. 1994. PMID: 7523293 Free PMC article.
As a model system, the hen egg white lysozyme 52-61 [HEL(52-61)] epitope, which binds the murine major histocompatibility complex class II (MHC-II) molecule I-Ak, was expressed in soluble fusion proteins in S. typhimurium. ...These data suggest that the efficiency of epito …

AgfD, the checkpoint of multicellular and aggregative behaviour in Salmonella typhimurium regulates at least two independent pathways.
Römling U, Rohde M, Olsén A, Normark S, Reinköster J. Römling U, et al. Mol Microbiol. 2000 Apr;36(1):10-23. doi: 10.1046/j.1365-2958.2000.01822.x. Mol Microbiol. 2000. PMID: 10760159
To detect additional components contributing to the multicellular morphotype in S. typhimurium, we constructed a mutant in agfD, the positive transcriptional regulator of the agfBA(C) operon encoding for fimbrial subunit proteins. ...Therefore, it was concluded that agfD r …
