Journal of bacteriology.J Bacteriol.2015 Sep;197(17):2831-9. doi: 10.1128/JB.00339-15. Epub 2015 Jun 22.
Salmonella enteric serovar Typhimurium, a major cause of food-borne illness, is capable of using a variety of carbon and nitrogen sources. Fructoselysine and glucoselysine are Maillard reaction products formed by the reaction of glucose or fructose, respectively, with the ε-amine group of lysine. W

Basal Body Structures Differentially Affect Transcription of RpoN- and FliA-Dependent Flagellar Genes in Helicobacter pylori.

Tsang J1, Hoover TR2.
Journal of bacteriology.J Bacteriol.2015 Jun;197(11):1921-30. doi: 10.1128/JB.02533-14. Epub 2015 Mar 30.
Flagellar biogenesis in Helicobacter pylori is regulated by a transcriptional hierarchy governed by three sigma factors, RpoD (σ(80)), RpoN (σ(54)), and FliA (σ(28)), that temporally coordinates gene expression with the assembly of the flagellum. Previous studies showed that loss of flagellar pro
