A broad-spectrum phage-encoded mechanism to disarm bacterial type IV filaments

Nathan A. Roberge, Paankhi Dave, Véronique L. Taylor…·Lori L. Burrows

This paper identifies Aqs1, a phage-encoded protein that inhibits type IV pilus function in multiple Gram-negative bacteria by targeting the PilB ATPase.

Twitching motility suppressors reveal a role for FimX in type IV pilus extension dynamics

Nathan A. Roberge, Nathan Yuen, Hanjeong Harvey…·Lori L. Burrows

The paper identifies suppressor mutations in Pseudomonas aeruginosa that restore twitching motility in fimX mutants, revealing FimX's role in regulating PilB ATP hydrolysis and pilus extension dynamics.
