UniProtKB description: Toxic component of a type II toxin-antitoxin (TA) system. Its toxic effect is neutralized by coexpression with cognate antitoxin ParD1 but no other ParD or RelB antitoxin. Low levels of wild-type toxin in the absence of antitoxin decreases the rate of cell growth, and results in death or loss of colony formation abilities and greatly elongated cells. Low levels of a mutant missing the last 4 residues leads to loss of cell division while cell elongation continues.
