Effects of divalent cations and mirubactin C on several MgSO4-dependent cell wall mutants. (A) Growth behavior of Bacillus subtilis 168CA (wt) and Δmbl, ΔmreB, Δ4 mutant (which lacks ponA and genes for the 3 other class A PBPs) on PAB plates in the presence of 20 mM MgSO4, 4 μg/ml mirubactin C and in the absence of any additive. (B) Phenotype of Bacillus subtilis mutants Δmbl and ΔmreB in the presence of MgSO4 and 4 μg/ml mirubactin C.
