Mn2+ dependent transformation of Bacillus subtilis.
The present study shows that transformation of Bacillus subtilis can proceed in the presence of Mn2+ instead of Mg2+ with equal efficiency. The crucial condition seems to be the Mn2+ concentration which should not exceed 0.025 mM. Binding, uptake and breakdown of donor DNA as well as its physicochemical fate in Mn2+ dependent transformation was investigated. No changes as compared to the standard procedure with Mg2+ were noticed. The possible source of errors in this kind of experiments is discussed.
