Specific Function: | Toxic component of a type IV toxin-antitoxin (TA) module. Interacts with cytoskeletal proteins FtsZ and MreB; inhibits FtsZ GTP-dependent polymerization and GTPase activity as well as MreB ATP-dependent polymerization. Binds to both the N- and C-terminus of FtsZ, likely blocking its polymerization. Overexpression results in inhibition of growth in liquid cultures and decrease in colony formation; these effects are overcome by concomitant expression of antitoxin CbeA (YeeU). In other experiments after 6 hours cells are lemon-shaped and by 24 hours those that have not lysed are spherical with diminished polar regions. Toxic effects are neutralized by cognate antitoxin CbeA, although there is no direct interaction between the 2 proteins. |
