Bacteroidales Secreted Antimicrobial Protein-1 receptor recognition is coupled to protease-activation to form bactericidal pores
Findings establish BSAP-1 as a receptor-targeted, protease-activated antibacterial MACPF toxin and provide a framework for understanding how gut Bacteroidales spatially restrict toxin activation to shape strain-level competition.
