New Tricks for Phages
In the latest issue of Molecular Cell, the Maxwell, Davidson and Moraes labs identify and characterize Aqs1, a multi-purpose DMS3 phage protein. Aqs1 binds and inhibits LasR, which is required for quorum sensing and the release of several anti-phage defenses in Pseudomonas aeruginosa. But that’s not all. Aqs1 also binds PilB, and thereby blocks pilus assembly. Since the bacterial pilus helps phage to infect, Aqs1 prevents further […]
