Inhibiting heme piracy by pathogenic Escherichia coli using de novo-designed proteins.

Nature communications Jul 9, 2025
Iron is an essential nutrient for most bacteria and is often growth-limiting during infection, due to the host sequestering free iron as part of the innate immune response. To obtain the iron required for growth, many bacterial pathogens encode trans...
