Amidase and lysozyme dual functions in TseP reveal a new family of chimeric effectors in the type VI secretion system.

Peptidoglycan (PG) serves as an essential target for antimicrobial development. An overlooked reservoir of antimicrobials lies in the form of PG-hydrolyzing enzymes naturally produced for polymicrobial competition, particularly those associated with the type VI secretion system (T6SS). Here, we report that a T6SS effector TseP, from , represents a family of effectors with dual amidase-lysozyme activities.
