This study identifies McpA as a chemoreceptor in Salmonella Typhimurium that mediates taxis to oxygen and reactive oxygen species, revealing the CZB domain's role in redox sensing.

The paper presents high-resolution structures of Helicobacter pylori TlpD, revealing how ligand-binding perturbations propagate through coiled-coils to regulate kinase interfaces.

This study evaluates AlphaFold 3's ability to model natural variants of Helicobacter pylori KatA, showing high accuracy for conservative substitutions but variable results for flexible or interface sites.

This study shows that indole in feces does not protect against Salmonella infection and may instead aid pathogen survival by attracting bacteria to low-competitor-density niches.
