Phage enzymes trigger bacteria’s self-destruct immune response

Researchers found that a protease produced by some bacteriophages cuts a bacterial sensor protein, activating the CBASS immune system. The infected bacterium then kills itself, which can stop the virus spreading to neighbouring cells, according to ScienceDaily and Genetic Engineering & Biotechnology News.

Bottom line — The Science study may help guide phage therapies, while offering clues to an immune pathway shared with humans.

  1. Genetic Engineering & Biotechnology News reports that CBASS detects the effects of a viral protein on a bacterial protein, rather than sensing viral genetic material directly.

  2. ScienceDaily says the bacterial response is a last resort: activation kills the infected cell.

  3. Sam Hobbs of University of Utah Health told ScienceDaily that CBASS is related to an immune pathway found in people.

  4. The research, titled “Phage proteases activate CBASS antiphage immunity”, was published in Science.
