Abstract:
:Certain group VIIIB transition metal compounds were found to inhibit cell division in Escherichia coli, causing marked filamentous growth. Gram-negative bacilli were the most sensitive to this effect, whereas gram-positive bacilli responded only at near-toxic levels of the metal. None of the cocci tested showed any apparent effect. Cytokinesis (cross-septation) can be initiated by removal or decrease of platinum, but not by treatment with pantoyl lactone, divalent cations, or a temperature of 42 C.

杂志文章abstract::Toxin-antitoxin (TA) loci consist of two genes in an operon, encoding a stable toxin and an unstable antitoxin. The expression of toxin leads to cell growth arrest and sometimes bacterial death, while the antitoxin prevents the cytotoxic activity of the toxin.
