Live-attenuated Listeria monocytogenes has shown encouraging potential as an immunotherapy platform in preclinical and clinical settings. However, additional safety measures will enable application across malignant and infectious diseases. Here, we d

Virulent Burkholderia Species Mimic Host Actin Polymerases to Drive Actin-Based Motility

Autor: Catherine M. Nguyen, Erin L. Benanti, Matthew D. Welch

Publikováno v: Cell, vol 161, iss 2

SummaryBurkholderia pseudomallei and B. mallei are bacterial pathogens that cause melioidosis and glanders, whereas their close relative B. thailandensis is non-pathogenic. All use the trimeric autotransporter BimA to facilitate actin-based motility,

Helicobacter pylori NikR Protein Exhibits Distinct Conformations When Bound to Different Promoters*

Autor: Peter T. Chivers, Erin L. Benanti

Helicobacter pylori NikR (HpNikR) is a ribbon-helix-helix (RHH) DNA-binding protein that binds to several different promoter regions. The binding site sequences are not absolutely conserved. The ability of HpNikR to discriminate specific DNA sites re

An intact urease assembly pathway is required to compete with NikR for nickel ions in Helicobacter pylori

Autor: Erin L. Benanti, Peter T. Chivers

Publikováno v: Journal of bacteriology. 191(7)

We examined the effects of urease and hydrogenase assembly gene deletions on NikR activation in H. pylori strains 26695 and G27. The loss of any component of urease assembly increased NikR activity under Ni 2+ -limiting conditions, as measured by red

The N-terminal arm of the Helicobacter pylori Ni2+-dependent transcription factor NikR is required for specific DNA binding

Autor: Peter T. Chivers, Erin L. Benanti

Publikováno v: The Journal of biological chemistry. 282(28)

The Ni(2+)-dependent transcription factor NikR is widespread among microbes. The two experimentally characterized NikR orthologs, from Helicobacter pylori and Escherichia coli, display vastly different regulatory capabilities in response to increased

Identification of Ni-(l-His)2 as a substrate for NikABCDE-dependent nickel uptake in Escherichia coli

Autor: Vanessa Heil-Chapdelaine, Peter T. Chivers, Jeffrey S. Iwig, Jessica L. Rowe, Erin L. Benanti

Publikováno v: Metallomics. 4:1043

Nickel is an important cofactor for several microbial enzymes. The ATP-dependent NikABCDE transporter is one of several types of uptake pathways known to be important for nickel acquisition in microbes. The Escherichia coli NikA periplasmic binding p
