PtuA and PtuB assemble into an inflammasome-like oligomer for anti-phage defense
{{output}}
Escherichia coli Septu system, an anti-phage defense system, comprises two components: PtuA and PtuB. PtuA contains an ATPase domain, while PtuB is predicted to function as a nuclease. Here we show that PtuA and PtuB form a stable complex with a 6:2 stoichiome... ...
