SNIPE bacterial defense system shreds phage DNA before infection can begin
The article describes a newly discovered bacterial defense system called SNIPE, which cleaves phage DNA before infection can occur. The research, conducted by MIT scientists and published in Nature, details how SNIPE's membrane-bound nuclease activity prevents phage genome integration into bacterial cells, offering insights into bacterial immunity mechanisms.
