CsrA and TnaB Coregulate Tryptophanase Activity To Promote Exotoxin-Induced Killing of Caenorhabditis elegans by Enteropathogenic Escherichia coli

Bhatt, Shantanu; Anyanful, Akwasi; Kalman, Daniel (JOURNAL OF BACTERIOLOGY,, 2011-09)

Enteropathogenic Escherichia coli (EPEC) requires the tnaA-encoded enzyme tryptophanase and its sub- strate tryptophan to synthesize diffusible exotoxins that kill the nematode Caenorhabditis elegans. Here, we demonstrate ...
A Family of Indoles Regulate Virulence and Shiga Toxin Production in Pathogenic E. coli

Bommarius, Bettina; Anyanful, Akwasi; Izrayelit, Yevgeniy; Bhatt, Shantanu; Cartwright, Emily; Wang, Wei; Swimm, Alyson I.; Benian, Guy M.; Schroeder, Frank C.; Kalman, Daniel (PLoS ONE, 2013-01-23)

Enteropathogenic Escherichia coli (EPEC), enterohemorrhagic E. coli (EHEC) and enteroaggregative E. coli (EAEC) are intestinal pathogens that cause food and water-borne disease in humans. Using biochemical methods and ...
Paralysis and killing of Caenorhabditis elegans by enteropathogenic Escherichia coli requires the bacterial tryptophanase gene

Dolan-Livengood, Jennifer M.; Lewis, Taiesha; Sheth, Seema; DeZalia, Mark N.; Sherman, Melanie A.; Kalman, Lisa V.; Benian, Guy M.; Kalman, Daniel (Molecular Microbiology, 2005)

Pathogenic Escherichia coli, including enteropatho- genic E. coli (EPEC), enterohaemorrhagic E. coli (EHEC), enteroinvasive E. coli (EIEC) and enterotoxi- genic E. coli (ETEC) are major causes of food and water-borne ...
