Enteric Escherichia coli survives the highly acidic environment of the stomach through multiple acid resistance (AR) mechanisms.  ...  Our data demonstrate that nac and csiR directly modulate AR, and leads to a regulatory network model in which all four TFs participate in coordinating acid resistance, glutamate metabolism, and nitrogen  ...  Acknowledgements The authors gratefully acknowledge the support of Dan Harkness. We thank the Wadsworth Center Applied Genomic Technologies Core Facility for Sanger sequencing.  ...

The Small Noncoding DsrA RNA Is an Acid Resistance Regulator in Escherichia coli

R. A. Lease, D. Smith, K. McDonough, M. Belfort
2004 Journal of Bacteriology  
E. coli K-12 strains, as well as pathogenic E. coli O157:H7, exhibited compromised acid resistance in dsrA mutants.  ...  Conversely, overproduction of DsrA from a plasmid rendered the acid-sensitive dsrA mutant extremely acid resistant. Thus, DsrA RNA plays a regulatory role in acid resistance.  ...  We appreciate the services of the Wadsworth Center Molecular Genetics and Genomics Core Facil-ities. Sarah Woodson provided laboratory resources, as well as valuable comments on the manuscript.  ...
