Reduced polysialic acid capsule expression in Escherichia coli K1 mutants with chromosomal defects in kpsF.
Cieslewicz M, Vimr E. Cieslewicz M, et al. Mol Microbiol. 1997 Oct;26(2):237-49. doi: 10.1046/j.1365-2958.1997.5651942.x. Mol Microbiol. 1997. PMID: 9383150
Antibodies raised against KpsF identified at least one of its paralogues in E. coli, GutQ, suggesting that KpsF and its homologues are membrane associated. ...

Redirection of sialic acid metabolism in genetically engineered Escherichia coli.
Ringenberg M, Lichtensteiger C, Vimr E. Ringenberg M, et al. Glycobiology. 2001 Jul;11(7):533-9. doi: 10.1093/glycob/11.7.533. Glycobiology. 2001. PMID: 11447132
Genetic hybrids of nonpathogenic, sialate-negative laboratory Escherichia coli K-12 strains designed for the de novo synthesis of the polysialic acid capsule from E. coli K1 proved useful in elucidating the genetics and biochemistry of capsule biosynthesis. ...The combined …

Strain-specific iron-dependent virulence in Escherichia coli.
Telang S, Vimr E, Mahoney JR, Law I, Lundqvist-Gustafsson H, Qian M, Eaton JW. Telang S, et al. J Infect Dis. 2001 Jul 15;184(2):159-65. doi: 10.1086/322017. Epub 2001 Jun 5. J Infect Dis. 2001. PMID: 11424012
The virulent E. coli strain had a polysialic acid-containing capsule, whereas the nonvirulent strain did not. Virulent E. coli grown at 20 degrees C (which blocks polysialylation) were cleared as rapidly as nonvirulent organisms. In another virulent E. coli s …

Sialic acid metabolism's dual function in Haemophilus influenzae.
Vimr E, Lichtensteiger C, Steenbergen S. Vimr E, et al. Mol Microbiol. 2000 Jun;36(5):1113-23. doi: 10.1046/j.1365-2958.2000.01925.x. Mol Microbiol. 2000. PMID: 10844695
The predicted H. influenzae homologue (HI0142) of the E. coli sialic acid aldolase structural gene, nanA, was subcloned and mutagenized by insertion of a kanamycin resistance cassette. Phenotypic investigation of the resulting H. influenzae aldolase mutants showed that: (i …

Thermoregulation of kpsF, the first region 1 gene in the kps locus for polysialic acid biosynthesis in Escherichia coli K1.
Cieslewicz M, Vimr E. Cieslewicz M, et al. J Bacteriol. 1996 Jun;178(11):3212-20. doi: 10.1128/jb.178.11.3212-3220.1996. J Bacteriol. 1996. PMID: 8655501 Free PMC article.
Steenbergen, and E. R. Vimr, J. Bacteriol. 175:8018-8023, 1993). A preliminary indication that kpsF is required for capsule production is the capsule-negative phenotype of an aph T insertion in the chromosomal copy of kpsF. ...However, since E. coli contains …

Derived structure of the putative sialic acid transporter from Escherichia coli predicts a novel sugar permease domain.
Martinez J, Steenbergen S, Vimr E. Martinez J, et al. J Bacteriol. 1995 Oct;177(20):6005-10. doi: 10.1128/jb.177.20.6005-6010.1995. J Bacteriol. 1995. PMID: 7592358 Free PMC article.
Catabolism of sialic acids by Escherichia coli requires the genes nanA and nanT, which were previously mapped between argG and rpoN (E.R. Vimr and F.A. Troy, J. Bacteriol. 164:845-853, 1985). This organization is confirmed and extended by physical mapping techniques …
