Type VI secretion systems (T6SSs) are nanomachineries used by bacteria to inject toxic effectors into neighbouring cells during interbacterial competition or infection. The existence of multiple paralogues of the structural proteins VgrG and PAAR and of specific accessory proteins allows the same T6...
Bacteria have evolved effectors or toxins to outcompete other bacteria or to hijack host cell pathways. One broad family of bacterial polymorphic toxins regroups multidomain proteins with a modular organization, that comprise a C-terminal toxin domain fused to a N-terminal domain that adapt to the d...
