NewsJumbo phages deploying secret handshakes could usher in new antibiotics
Jumbo phages create a restricted space inside bacteria where they can copy their DNA while surrounded by a protective shield. A new study reveals that the shield works via a set of ’secret handshakes’, allowing only a specific set of useful proteins to pass through.
