Merry Youle of the Small Things Considered blog has a new post up that looks at the phage-encoded holin timer and its function in a lytic infection.
"Holins are the smallest known biological timers. Timers, not clocks. Timers tick along, then go off after the specified interval. These small, phage-encoded proteins time the length of lytic infections of some phages. When they go off, the game is over and the host cell lyses. This is important work. The phage that gets the timing right is one-up in the evolutionary race."
