Fig. 6. S100A12 exhibits antibacterial activity against E. coli with defective Zn(ii) uptake machinery in TSB/Tris medium. (A) Antibacterial activity of S100A12 against E. coli K-12. (B) Antibacterial activity of S100A12 against E. coli K-12 ΔznuA. Black, E. coli treated with S100A12 in the absence of a Ca(ii) supplement. Red, E. coli treated with S100A12 in the presence of ≈2 mM Ca(ii). The OD600 values were recorded at t = 20 h (mean ± SEM, n = 3).
