The paper structures ZmaM, a type II peptidase-ABC transporter in B. cereus, showing it activates and exports zwittermicin A by coordinating peptidase and transporter modules.

This study investigates microbial dysbiosis in children with cystic fibrosis, identifying glycerol as a driver of altered microbial competition and linking colibactin production to increased colorectal cancer risk.

The paper discovers a new class of bile salt hydrolases in the human gut microbiome that use metal cofactors instead of the typical Ntn mechanism.

This study develops chemiluminescent probes to rapidly detect colibactin-producing bacteria in stool samples, showing improved sensitivity and speed over fluorescent alternatives.

This study shows that colibactin from the honeybee symbiont Frischella perrara defends against pathogens and influences gut microbial community structure.

This study determines the structure and specificity of colibactin-DNA interstrand crosslinks using mass spectrometry and NMR, revealing how the toxin's central motif mediates sequence specificity.
