| Description | Toxin YqcG is a toxic component of LXG toxin-immunity modules, which promote kin selection, mediate competition in biofilms, and drive spatial segregation of different strains, indicating that LXG toxins may help avoid warfare between strains in biofilms. It mediates intercellular competition during biofilm formation; disruption of the operon disadvantages the bacteria, but overexpression of the cognate immunity protein restores growth in competition with wild-type. Overexpression alone in situ causes growth arrest but not cell lysis, a large decrease in chromosomal DNA content and the production of anucleate cells. The toxic effect is dependent on the epsA and tapA operons which are required for biofilm formation [ ]. This entry represents the C-terminal nuclease domain. | Name | Toxin YqcG, C-terminal |
